At Precisely, I optimized backend APIs and reduced Node.js event loop lag from 1500ms to under 50ms in the worst-case scenario. I also enhanced the MongoDB migration framework with pause, resume, and failure-recovery capabilities.
At Nagarro, I improved Suzuki Dealer Management System performance by up to 40% by migrating business logic to PostgreSQL stored procedures. I also implemented Redis caching and strengthened reliability with Jest tests.
At Polysports, I built a Zomato-like dining application with customer and admin modules, and deployed payment services on AWS ECS. Across my work, I’ve developed backend services, SaaS platforms, and web applications using Node.js and distributed-system technologies.
