Data warehousing & architecture

Turnkey Analytical DWH

I bring all of your business data together into one reliable warehouse on Google BigQuery or ClickHouse — the foundation for dashboards, end-to-end analytics and decision-making.

What is DWH

A Data Warehouse is a centralised system that regularly collects and harmonises data from all of your business sources: CRM, accounting, ad platforms, website and app. It becomes the basis for all reporting and analytics — with no manual exports and no discrepancies in the numbers.

When you need this

Data is scattered across dozens of systems, and every department calculates metrics its own way
Reports are assembled by hand in Excel and are already out of date by the time they're ready
You need a single, trustworthy set of reports for management and investors
Data volumes are growing, and your current solutions can no longer keep up
You want to build end-to-end analytics or ML, but there's no foundation of clean data

What's included

Data ingestion from any source

Ready-made connectors and custom integrations to CRM, accounting systems, ad platforms, your website and app.

Processing and modelling

Cleansing, normalisation and building data marts with dbt — data is ready to use in dashboards.

Orchestration

Automated scheduled loads on Apache Airflow or Prefect, with schedules and dependencies.

Quality control

Integrity and data-quality checks at every step of the pipeline.

Alerting

Telegram notifications about integration failures and important changes in the data.

BI visualisation

Dashboards in Google Looker Studio or Metabase on top of the finished warehouse.

How it works

  1. 01

    Discovery and pre-project analysis

    We review data sources, metrics and reporting requirements, and lock down the architecture.

  2. 02

    Warehouse design

    We choose the database (BigQuery/ClickHouse) and design the layers and data model.

  3. 03

    Integrations and ingestion

    We connect the sources and set up scheduled loads and orchestration.

  4. 04

    Data mart modelling

    We build data marts on dbt tailored to specific dashboards and tasks.

  5. 05

    Visualisation and acceptance

    We create dashboards, verify the numbers are correct, and hand them over for use.

  6. 06

    Support

    I keep the DWH running reliably and continue to evolve it.

Testimonials

«Quickly and precisely built dashboards in a BI tool according to the spec. A few months after the work was done, we made changes to our databases and the dashboards broke. Rustam advised us for free and got everything working again. Recommended!»

A data warehouse is the foundation on which a company’s entire analytics rests. I design and build the DWH so that the numbers are trustworthy, reports stay current, and adding new sources and dashboards never turns into a headache.

Pricing

Pricing is calculated individually and depends on the scope and complexity of the project.

Number of data sources
The more systems that need to be integrated, the larger the scope of work.
Complexity of integrations
Whether ready-made connectors exist or custom development is required.
Data volume and model
The depth of data-mart modelling and requirements for historisation.
Number of dashboards
The number and complexity of reports on top of the warehouse.

FAQ

Which database do you build the DWH on? +

Most often on Google BigQuery or ClickHouse — the choice depends on data volume, budget and speed requirements. During the pre-project analysis we'll pick the best option.

How long does implementation take? +

A basic warehouse with the first integrations and dashboards — from a few weeks. Exact timelines depend on the number of sources and the complexity of the data.

What happens after launch? +

I provide technical support for the DWH and dashboards, and refine integrations and reports as the business grows.
