I've built backend systems and machine-learning services across Arizona State University, Naturesmith Foods, and Indian Oil Corporation.
At EPICS at Arizona State University, I built stateless JWT authentication with role-based access control for more than 100 system design problems. I also developed RESTful microservices for profiles, progress tracking, and practice analytics, with CI workflows supporting validation and testing.
At Naturesmith Foods, I resolved inventory race conditions with serializable PostgreSQL transactions and reduced inventory API latency by 25% through query optimization, indexing, and cursor-based pagination.
At Indian Oil Corporation, I built predictive-maintenance models that reached 96.73% machine-failure detection accuracy and delivered real-time predictions through FastAPI, Redis Streams, and a React.js dashboard, reducing unplanned downtime by 33%.
