I architected and owned an end-to-end, fault-tolerant ETL pipeline at Convegenius that ingests 100M+ government education records daily across 6+ Indian states, with PostgreSQL transactional staging and rollback to keep 99.9% data consistency.

I also built a column-level differential reconciliation engine for MIS vs UDISE data, migrating past materialized view upsert limitations to indexed PostgreSQL tables with a pre-aggregated summary layer—cutting processing from hours to minutes.

Across multiple pipelines, I centralized log management and observability into a unified real-time dashboard, and implemented production-grade recovery with exponential backoff retries, health checks, AWS CloudWatch logging, and Slack webhook integration.

Before that, at TravelCorporationofIndia I helped deliver React-based products like a theme-editor, integrated AWS Cognito for authentication, built backend/mobile guide integrations, and improved guide search performance by 2.35 seconds.
