What I'm looking for

I'm looking to build scalable, secure web applications and backend platforms, with opportunities to own API and data-model design, improve asynchronous workflows, and collaborate across teams on production-ready software.

At Citi, I build Python REST APIs with PostgreSQL for more than 10,000 daily payment transactions, improving validation speed and reducing errors by 15%. I also use Celery, Redis, and AWS SQS to deliver durable asynchronous payment workflows.

Previously at Optum, I optimized PostgreSQL schemas and Python backend services for eligibility workflows, reducing query latency by 35% and failure rates by 25% through resilient task processing and retry logic.

At TCS, I built Django REST Framework APIs for order and inventory workflows, strengthened authentication and role-based access control, integrated payment and shipping APIs, and improved testing, error handling, and deployment processes. I enjoy architecting scalable, testable web applications that are secure, maintainable, and ready for production.
