Projects

Each project solves a problem businesses actually have, runs live on this site and is written up with its architecture, measured results, failure handling, cost and limitations.

LiveData engineering

Data Pipeline Observatory

Problem
Monthly exports, a product master and a CRM API never agree. Duplicates, cancellations, stock write-offs and missing customer IDs silently corrupt every report built on them.
Solution
A Python pipeline that validates each row against a data contract, quarantines bad rows with reason codes, loads PostgreSQL idempotently and refuses to publish when a quality gate fails.
