At LSEG, I build modular Python and Pytest data-testing frameworks for financial pipelines, schema contracts, and API integrations across Databricks and AWS S3.
I've automated batch and near-real-time validation for anomalies, schema drift, nulls, record drops, and SLA freshness, while embedding Dockerized quality gates in GitHub Actions and Jenkins to stop corrupted records before production. I also use advanced SQL and Python to verify multi-source joins, identity alignment, record counts, and transformations.
Previously, I led six engineers at Amadeus and reduced critical production defects by 40%. Across Evry, ALSTOM, and TCS, I've delivered API, database, performance, and cloud-based automation for data-intensive systems.
