Analytics & BI Modernization

Trustworthy numbers for the whole company.

We rebuild the numbers layer: a versioned semantic model, tested dbt transformations and a BI stack that business users actually trust — with documented lineage from raw source to dashboard.

What we ship

Capabilities

dbt-driven semantic layers, warehouse migrations (Snowflake / BigQuery / ClickHouse) and BI rebuilds that finally give every team the same definition of revenue.

  • 01

    dbt models, tests & docs

    Every transformation versioned in Git, tested with dbt expectations and documented with column-level lineage — no more mystery SQL in the warehouse.

  • 02

    Semantic layer & metric catalogues

    One definition of revenue, conversion and churn — exposed to BI tools through a semantic layer so every dashboard agrees on the numbers.

  • 03

    Snowflake / BigQuery / ClickHouse

    We migrate from legacy EDW platforms and optimize for your query patterns — ClickHouse for high-concurrency analytics, BigQuery for cloud-native scale.

  • 04

    Self-serve BI in Metabase / Looker

    Business users write their own questions — against a semantic model with guardrails — without going through the data team for every report.

Outcomes

  • One trusted definition of core KPIs
  • Documented, testable transformations
  • Self-serve analytics across teams

How we deliver

Our delivery process

Every engagement follows the same rigorous four-stage approach — so you know exactly what to expect, and when.

  1. Step01

    KPI alignment workshop

    We run a structured session with finance, product and ops to agree on canonical metric definitions before touching the warehouse.

  2. Step02

    dbt model build

    Staged, tested dbt models from raw source to gold-layer business entities — reviewed and signed off by domain owners.

  3. Step03

    Warehouse migration

    Parallel-run validation between legacy and new warehouse until every dashboard shows identical numbers — then cutover.

  4. Step04

    BI training & handoff

    Business users trained on self-serve BI with governed semantic models — data team freed from report requests.
