Business Intelligence & Data (ETL / DWH)

For most modern companies, data is no longer a “nice to have”. It is the nervous system of the business: every sale, every campaign, every support ticket and every product interaction leaves a trace. The problem is rarely a lack of data. The real problem is that data is scattered, inconsistent or simply not trusted enough to drive decisions.


At khajavi.tech, we focus on Business Intelligence & Data (ETL / DWH) as a core service. Led by Mehdi Khajavi, we help teams move from spreadsheets and disconnected tools to a coherent data platform: clean pipelines, a well-designed data warehouse, meaningful dashboards and a shared language around KPIs. The goal is simple: give your team the numbers they can rely on, exactly when they need them.

What Do We Mean by Business Intelligence?

Business Intelligence (BI) is the discipline of turning raw data into insight that people can actually use. It is not just a dashboard tool or a report. BI is the full chain from how data is generated to how decisions are made.

In a robust BI setup:

  • Data is generated in systems: website, product, CRM, ERP, support, marketing, finance.
  • Data is extracted, transformed and loaded (ETL / ELT) into a central store.
  • A data warehouse organizes that information into clean, connected models.
  • Dashboards, reports and self-service tools bring those models to life.
  • Teams learn to read, question and act on the numbers together.

When BI is done well, your team stops arguing about “which number is correct” and starts discussing “what we should do next”. That shift is often the difference between instinct-driven decisions and repeatable, data-informed growth.

In practice, modern Business Intelligence involves far more than “adding a dashboard” to your stack.

A clear data and BI strategy
– which questions matter most, which decisions need better information, and how BI supports your growth.
Reliable ETL / ELT pipelines
– jobs that consistently move data from source systems into your analytics environment without surprises.
A well-designed data warehouse
– models that reflect your real business entities and flows, not just raw dumps from tools.
Analytics and dashboards that people can actually use
– views built around concrete decisions, with clearly defined metrics and drill-downs.
Data quality, governance and trust
– checks, monitoring and shared definitions so people believe the numbers and use them confidently.

At khajavi.tech, Business Intelligence & Data work is the discipline of getting all of these layers to work together so that data feels simple to your users and controllable to your team.

BI Overview

Types of Business Intelligence & Data Projects We Deliver

Because we combine application engineering, BI and database performance expertise, we tend to work on data platforms that are more than “just a dashboard”. Typical Business Intelligence & Data projects at khajavi.tech include:

BI Platform

1. End-to-End BI Platforms

From discovery and data architecture to ETL, warehouse and dashboards, we design and implement complete BI platforms. The result is a coherent environment where data flows cleanly, KPIs are defined once and teams use the same source of truth for decisions.

ETL Pipelines

2. ETL / ELT Pipelines & Data Integration

We design ETL / ELT processes that move data from product databases, CRMs, marketing tools, finance systems and more into your analytics stack. Jobs are predictable, logged and auditable, with clear schedules and error handling so you can trust data freshness.

Data Warehouse Architecture

3. Data Warehouse Architecture & Modeling

We design data warehouses that reflect your business: customers, products, orders, subscriptions, campaigns and more. Fact and dimension tables, key strategies and aggregation layers are chosen so that analysts and stakeholders can answer questions without fighting the schema.

Dashboards and Analytics

4. Dashboards, Reports & Self-Service Analytics

We build dashboards around real decisions: what sales needs in the morning, what leadership reviews monthly, what operations monitors in near-real-time. Metrics are defined explicitly, so every chart tells a clear story and new team members can understand it with minimal onboarding.

BI Modernization

5. BI Modernization & Migrations

If your current BI setup is a tangle of spreadsheets, fragile reports and untrusted metrics, we help you move to a modern platform. Sometimes that means refactoring ETL and models; sometimes it means migrating off legacy stacks with a carefully planned, low-risk transition.

Our Business Intelligence & Data Approach at khajavi.tech


Tools and frameworks matter, but they are not where we start. Our BI & Data work begins with understanding your business, your teams and your constraints – and then designing a data platform that supports real decisions across product, marketing, operations and finance.

Discovery

1. Discovery: Questions Before Data

We begin with focused conversations, not tools. In discovery, we clarify:

  • Which decisions you are making regularly that feel “blind” or based on intuition only.
  • Which recurring reports are painful to prepare or impossible to trust.
  • Which teams feel the most frustrated about data and why.
  • Which KPIs are considered “official”, and who defines them today.

The outcome is a short map of use cases and questions that BI should help answer. This becomes the backbone of our design.

Architecture

2. Data Landscape & Architecture

Next, we map your current data landscape:

  • Product and application databases.
  • CRM, marketing, support and finance tools.
  • Existing exports, spreadsheets and ad-hoc scripts.
  • Any partial BI or reporting setups already in place.

We then propose an architecture that fits your scale and ambitions. Sometimes a single, well-structured warehouse and a few pipelines are enough. Sometimes you need a more layered approach with staging, core and data-mart layers. The goal is always clarity, not buzzwords.

ETL Design

3. ETL / ELT Design & Implementation

Based on your sources and chosen architecture, we design ETL / ELT jobs that:

  • Extract only what is needed, on a sensible schedule.
  • Transform data into consistent formats and structures.
  • Load into staging and then curated warehouse layers.
  • Include logging, error handling and monitoring.
  • Are modular enough to adapt when sources change.

We prefer predictable, well-named jobs and clear folder structures over opaque “magic” pipelines. This makes it easier for your team to understand and extend the system.

Data Modeling

4. Data Modeling & Metric Definitions

Once core data is flowing, we design the logical models and metrics your teams will use:

  • Fact tables for orders, sessions, transactions, tickets, invoices and more.
  • Dimension tables for customers, products, plans, campaigns, channels and other entities.
  • Standardized definitions for revenue, churn, retention, cohorts and funnel stages.
  • Aggregated views for metrics like daily active users or recurring revenue.

This modeling step is where much of the long-term value is created. Once definitions are encoded in the warehouse, every dashboard and report can reuse them.

Dashboards and Access

5. Dashboards, Reports & Access

With a solid data model, we design dashboards and reports around the use cases identified in discovery. We start from questions, not charts: What should sales see each morning? What does the CEO look at monthly? What does support need in real time?

We also work with you to define access control: who sees which datasets, how roles and permissions are managed and how sensitive data is protected.

Data Literacy and Support

6. Data Literacy & Ongoing Support

BI fails when only one or two people understand how things work. We prefer to share that understanding widely:

  • Walkthrough sessions with your teams to explain models and dashboards.
  • Short documentation of key concepts and metrics.
  • Regular check-ins to refine dashboards as your questions evolve.

Through a retainer or dedicated pod model, khajavi.tech can stay close to your data platform: updating pipelines, adding new sources and helping you grow your BI capabilities over time.

Non-Functional Requirements: The Part of BI & Data You Don’t See in Dashboards


Dashboards do not tell you whether a Business Intelligence platform is robust. Non-functional requirements are the characteristics that determine how your data system behaves when things are not ideal: schema changes, traffic spikes, delayed sources or bad data. We treat these as first-class citizens in our BI & Data work.

Pipeline Performance & Scalability

A BI platform is only useful if data arrives reliably and on time. We design for performance and scalability across your data pipelines:

  • Efficient extraction that minimizes load on source systems.
  • Incremental loads instead of heavy nightly full reloads where possible.
  • Well-indexed warehouse tables tuned for analytical workloads.
  • Simple caching and aggregation strategies for frequently used views.
  • Scalable infrastructure that can grow with data volume and usage.

Security, Governance & Compliance

Your BI platform holds some of your most sensitive information. We implement:

  • Role-based access control for datasets and dashboards.
  • Row-level security patterns where data must be segmented.
  • Careful handling of credentials, secrets and connection details.
  • Separation of environments for development, staging and production.
  • Governance around who can define or change core metrics.

Maintainability & Extensibility of Your Data Platform

A quick patch may seem fine for a one-off report, but it becomes expensive once many teams depend on BI. We aim for designs and implementations that:

  • Are understandable to engineers and analysts joining later.
  • Allow new metrics and sources without breaking existing logic.
  • Work well with automated tests, CI/CD and version control.
  • Keep transformations and business logic in the right layers.

How Business Intelligence & Data Connect to Your Product and Operations


One of the unique aspects of khajavi.tech is the combination of web application development with Business Intelligence, data warehousing and database performance engineering. For many products, the real value lies in how data flows through the system and how it can be used for decision-making.



When we design a BI & Data platform, we think about:


  • What data should be captured at each step of the user and customer journey.
  • How that data is stored and modeled in application and warehouse tables.
  • How we can feed that data into a data warehouse or BI platform reliably.
  • What dashboards or reports will be needed by leadership, operations and product.
  • How we maintain data quality and consistency as the product and organisation evolve.
This means your BI platform is not just a reporting layer – it is part of a larger data system that supports growth, forecasting and strategic decisions.


Use Cases: Where Our Business Intelligence & Data Services Fit Best


While nearly every company can benefit from better data, there are recurring patterns where our BI & Data work has an outsized impact:
  • eCommerce and retail – unifying orders, inventory, campaigns and customer behaviour into a single view.
  • SaaS and B2B products – tracking cohorts, usage, onboarding, retention and revenue with consistent metrics.
  • FinTech and data-sensitive products – designing traceable, auditable BI setups with clear lineage.
  • Operations, logistics and manufacturing – connecting planning, execution and outcomes with actionable dashboards.
  • EdTech products – combining learning content, assessments, engagement and admin panels into a single data picture.
If your situation involves complex data, multiple teams and the need for reliable reporting, Business Intelligence & Data work with khajavi.tech is a strong match.


Approach and philosophy

Working with Startups

Startups often have plenty of data sources but very little structure. We help you:

  • Pick a small but crucial set of KPIs to start with.
  • Design an initial warehouse and ETL setup that can grow later.
  • Instrument your product so key events are captured correctly.
  • Prepare for investor conversations with numbers you can stand behind.


Working with Established Organizations

Larger companies usually have reports, but they are scattered and inconsistent. We help you:

  • Map existing reports and metrics across departments.
  • Consolidate overlapping definitions and sources of truth.
  • Design a central data warehouse that supports many teams.
  • Plan migrations away from fragile legacy reporting stacks.


How We Measure the Success of a BI & Data Project


For Business Intelligence & Data work, success is not “we set up a data warehouse”. Success is when teams across your company:
  • Use the same dashboards instead of sharing screenshots from different tools.
  • Trust that numbers will be available and correct when they need them.
  • Spend less time cleaning data and more time interpreting it.
  • Can answer new questions quickly using existing models and pipelines.
  • See a direct link between better data and better outcomes: revenue, efficiency, quality.
We design projects so these outcomes are not accidental but built into the way your BI platform is structured and operated.


Engagement Models for Business Intelligence & Data with Khajavi


Depending on where you are in your data journey, we can collaborate in different ways:
  • End-to-end BI implementation – from discovery to ETL, data warehouse and dashboards.
  • Data warehouse or ETL modernization – focusing on cleaning up or re-architecting an existing platform.
  • Performance and database audit – targeting bottlenecks and reliability issues in your data stack.
  • Ongoing data & BI support – a retainer or pod to keep your platform evolving with the business.
  • Targeted advisory – focused sessions to review architectures, metrics and roadmaps.


How to Get Started


If you feel that your data is underused, unreliable or simply overwhelming, a structured BI and data initiative can change that. The first step is simple: a conversation. Share how you currently work with data, what frustrates your teams and what you wish you could see clearly. From there, khajavi.tech can outline a practical Business Intelligence & Data plan: the questions we will help you answer, the architecture we recommend and the steps to get from where you are today to a BI platform that your company actually enjoys using.



Business Intelligence & Data (ETL / DWH) – Frequently Asked Questions


1. What is Business Intelligence in practical terms?

Business Intelligence is the end-to-end process of turning raw data from your systems into useful insight for people. It covers data collection, ETL, data warehousing, modeling, dashboards and the habits around using those dashboards in daily decisions. In practice, it means your team can answer important questions with confidence, using a shared source of truth instead of scattered spreadsheets.

2. How is Business Intelligence different from simple reporting?

Simple reporting usually means exporting data from a single system and formatting it in a spreadsheet or a basic chart. Business Intelligence connects multiple systems, standardizes definitions, stores data in a warehouse and provides reusable models and dashboards. BI is designed for repeatable, cross-functional questions, not just one-off summaries.

3. What does khajavi.tech include in its BI & Data services?

khajavi.tech covers discovery, data architecture, ETL / ELT design and implementation, data warehouse modeling, metric definitions, dashboard design, data quality checks and ongoing support. We also connect BI with your web applications and product so the analytics layer grows alongside your core systems.

4. Which data sources can you integrate into a BI platform?

We can work with product and application databases, CRMs, marketing tools, ad platforms, support systems, financial systems, warehouse or logistics tools and more. The key is to decide which systems are sources of truth for each type of data and then design ETL processes that bring them together reliably.

5. What is a data warehouse and why do I need one?

A data warehouse is a structured, long-term store for analytics data. Instead of pulling data separately from each operational system, you load it into the warehouse where entities and metrics are standardized. This makes it much easier to create consistent dashboards, support complex analyses and avoid conflicting definitions across teams.

6. What is ETL and how does it fit into Business Intelligence?

ETL stands for Extract, Transform, Load. It is the process of pulling data from source systems, cleaning and reshaping it and loading it into your data warehouse or analytics environment. ETL is the plumbing that feeds your BI platform. If ETL is unreliable or unclear, your dashboards and reports will be as well.

7. What is the difference between ETL and ELT?

In ETL, data is transformed before it is loaded into the warehouse. In ELT, data is loaded first, then transformed inside the warehouse using its processing power. The choice depends on your tools, data volumes and design preferences. We work with both patterns and choose what best fits your context.

8. How long does it take to implement a BI & Data solution?

Timelines depend on the number of data sources, the state of your current systems and the complexity of your questions. A focused setup with a few sources and key dashboards can be delivered in weeks, while a full multi-team platform can take several months. During discovery, we define a staged roadmap so you see value early instead of waiting for a “big bang” launch.

9. Do you only work with large companies on BI projects?

No. We work with both early-stage startups and established organizations. With startups, the focus is often on building a lean but solid foundation. With larger companies, the work usually involves consolidation, standardization and modernization of existing BI and reporting setups.

10. Can you help if we already have a BI tool but are not happy with the results?

Yes. Many teams have a BI tool license but lack a coherent data model or reliable pipelines. We can audit your current setup, refine the data warehouse, redesign metrics and rework dashboards so the tool is finally used to its potential. Often the problem is not the tool itself, but the way data is prepared for it.

11. How do you ensure data quality and trust in the numbers?

We define clear metric definitions, design consistent models and implement data quality checks. These checks cover volumes, valid values, relationships between tables and the timeliness of data. We also set up monitoring and alerts so issues are detected early. Over time, this builds confidence in the BI platform.

12. What industries are best suited for BI & Data services from khajavi.tech?

We work best with data-driven companies in eCommerce, SaaS and B2B, FinTech, logistics, manufacturing and EdTech. If your teams depend on digital systems and you feel that you are not fully using the data they produce, BI & Data work with khajavi.tech is likely to be valuable.

13. How does BI connect to my existing web application or product?

Your web application is often the main generator of customer and usage data. We connect application databases and events to your data warehouse, define product metrics and build dashboards that show how people actually use your product. Because khajavi.tech also builds web apps, we can design both layers to work well together.

14. Can you handle database performance issues related to BI workloads?

Yes. We have experience optimizing databases, especially SQL-based systems, for both transactional and analytical workloads. This includes index design, query optimization, partitioning strategies and caching where appropriate. The goal is to keep both your application and your BI platform responsive.

15. Do you support real-time or near real-time dashboards?

In some use cases, daily or hourly updates are enough. In others, near real-time insight is important. We can design architectures that support more frequent updates or streaming patterns where it makes sense, while being honest about the trade-offs in complexity and cost.

16. How do you handle security and access control in a BI platform?

We design access control so that people see the data they need and nothing more. This includes role-based access, row-level security where necessary and careful management of credentials. We also consider how sensitive fields are stored and who can access raw versus aggregated data.

17. Can our non-technical teams use the BI platform without help?

That is the goal. We design dashboards and data models so that non-technical users can answer common questions on their own. For more advanced analysis, your data or analytics team can build on top of the same models. We also provide walkthroughs and documentation to help teams become more confident with data.

18. How do you choose the right BI and data tools for a project?

We start from your requirements, existing stack and internal skills. Then we evaluate which tools fit best in terms of capabilities, cost and maintainability. We avoid introducing new tools when existing ones can do the job, and we focus on stable, well-supported technologies over hype.

19. What is the role of KPIs in a BI project?

KPIs (Key Performance Indicators) are the metrics that matter most for your business. In a BI project, we work with you to define these KPIs precisely, encode them in the data warehouse and use them as anchors for dashboards and reports. Clear KPIs turn raw data into a shared understanding of progress and health.

20. Can you help us move away from manual spreadsheet reporting?

Yes. A common starting point is to identify the most painful recurring spreadsheets, then recreate them on top of a data warehouse with automated pipelines. This reduces manual work, eliminates copy-paste errors and makes updates automatic instead of a monthly struggle.

21. How do you manage changes to data sources over time?

Source systems evolve: fields are added, renamed or removed. We design ETL and models with versioning and testing in mind, so changes can be detected early and handled in a controlled way. Communication with your internal teams about planned changes is also part of the process.

22. Do you offer ongoing support after the initial BI implementation?

Yes. Many clients keep working with khajavi.tech on a retainer or dedicated pod basis. We maintain pipelines, extend models, build new dashboards, onboard new teams and support leadership with new analyses as your business evolves.

23. Can you help our leadership team define a data strategy?

We can facilitate conversations with leadership to clarify how data should support your strategy: which decisions need better information, which metrics should be tracked, what level of granularity is appropriate and how BI fits into your long-term roadmap. The output becomes a practical, prioritized data strategy.

24. How do you handle historical data and backfilling?

When possible, we import historical data to give context to current metrics. This may involve one-time backfills from archives, legacy systems or exported files. We design backfill processes carefully to keep them auditable and repeatable if needed.

25. What if we are not sure where to start with BI?

That is a common situation. We usually begin with a light discovery phase, identify a small set of high-impact use cases and build a focused initial BI setup around them. Once that is working and delivering value, we can expand the platform step by step instead of trying to solve everything at once.

26. Can you work with our existing analytics or data team?

Yes. We often collaborate with internal data engineers, analysts and product teams. We can help design architectures, implement complex pieces, pair on tricky problems and transfer knowledge so your internal team becomes stronger over time rather than dependent on external help.

27. How do you communicate during a BI project?

We combine regular calls with async updates, shared documentation and clear project boards. You see what has been done, what is in progress and what is next. Trade-offs and decisions are documented so your team has a permanent record, not just chat history.

28. What does a typical BI engagement with khajavi.tech look like?

A typical engagement starts with discovery, moves into architecture and design, then ETL and DWH implementation, followed by dashboarding and enablement. From there, we either hand over a stable platform to your team or continue as an ongoing partner to evolve and maintain it.

29. What do you need from us to start a BI & Data project?

We need access to relevant systems or exports, a clear point of contact, and an honest view of your pain points and expectations. The more context you can share about how decisions are made today and where data feels unreliable, the better we can design a BI solution that actually fits your reality.

30. How can we talk to you about Business Intelligence & Data work?

You can reach out via the contact options on khajavi.tech, WhatsApp or email. Share a short description of your business, current data situation and what you hope BI will help you achieve. We will respond with suggested next steps and, if it makes sense, schedule a focused discovery call to explore the project together.
