Message

At GTET, The Narayana Group, I design and develop RESTful microservices for nLearn and nKids, platforms serving 500K+ users. I’ve improved API latency by 40% and helped maintain 99.9% uptime through Redis caching, asynchronous processing, and backend observability.

I also contributed to moving legacy systems toward modular microservices and developed reusable npm modules for internal services. At NSPIRA, I developed Node.js and PostgreSQL APIs for internal applications, including student assessment and notification workflows.
