Data engineering and analytics
Tankar builds the data layer between your operational systems and the people who need answers, including scheduled pipelines, a warehouse with a tested data model, dashboards, and forecasts where the history supports them. The same pipeline discipline runs TenderBazaar, which collects and normalises tender listings from Indian government portals.

From systems to answers
Operational systems produce data as a side effect. Turning it into answers takes pipelines that run on a schedule, a data model with one definition per metric, and dashboards people actually open. Tankar builds that layer and tests it like software.
Proof from our own products
TenderBazaar collects listings from Indian government portals, normalises them to one schema and serves search and alerts from the result. That pipeline discipline is what client data platforms get.
Governed, not ad hoc
Every metric is defined once and documented. Every pipeline run is tested. When a source changes, the tests fail before the dashboard lies.
Typical engagements
What this service usually produces, as deliverables rather than adjectives.

- Management dashboards with definitions everyone agrees on and alerts on the numbers that matter

Stack for this service
The technologies this work is usually built on, and why each one is used here.
| Technology | Why we use it here |
|---|---|
| Data pipelines (Airflow, dbt) | Scheduled, tested, versioned transformations instead of scripts nobody dares to touch. |
| PostgreSQL | The warehouse for small and medium data volumes, with one database to secure and back up. |
| Warehouses and dashboards (BigQuery, Snowflake, Metabase, Power BI) | A cloud warehouse when volume or concurrency outgrows PostgreSQL; Metabase or Power BI for dashboards the whole company can use. |
| Python and FastAPI | Collectors, normalisers and forecasting models in the language the data ecosystem is built in. |
| GitHub Actions | Pipeline changes are tested and deployed like application code. |
