At Tata Consultancy Services, I build and maintain FastAPI REST services for customer onboarding, application submission, document workflows, and decisioning.
I've strengthened production APIs with Pydantic validation, JWT authentication, RBAC, API versioning, idempotency, retries, and correlation IDs. My work reduced invalid-request failures by 40% and achieved up to 98% successful completion during transient downstream failures.
I optimize database-driven workflows across PostgreSQL and Oracle, using execution-plan analysis, indexing, and connection-pool tuning to reduce database load by 40%. I also work with Kafka, Docker, CI/CD, structured logging, health checks, and production troubleshooting.
Earlier, I built Flask APIs and data-processing utilities, automated extraction from 10+ external sources, and processed 100K+ records daily with Python and Pandas. I also build projects such as an incident-management platform and a multi-document RAG assistant with hybrid retrieval and evaluation workflows.
