- Architected a configurable data quality framework with 8 rule-based validators, integrated into a React grid with cell-level failure rendering and profiling dashboards - reducing manual error triage by 70%.
- Led end-to-end development of an Audit Service for Installed Base Data Studio, capturing every job and data flow with dashboard visibility from creation to persistence - reducing debugging time by 40%.
- Built a full-stack deduplication platform enabling analysts to iteratively merge, split, and edit customer location clusters across 10-100M records - a previously impossible capability at that scale.
- Replaced heavy PostgreSQL views with materialized views and precise indexing, reducing query fetch time by 87% and data processing time by 75%; migrated 100+ stored procedures and 6+ microservices from MySQL to PostgreSQL.
