Message

At Orvantis Technologies, I architected Node.js APIs and MongoDB services for real-time gaming and trading workflows, supporting 50K+ concurrent users and 30K requests per minute. I also reduced P95 latency from 250ms to 110ms.

I engineered WebSocket and Redis Pub/Sub pipelines, and shipped payment, wallet, and transaction modules with safeguards against duplicate processing. At Harappa Learning Private Limited (upGrad), I tuned learning APIs and launched Elasticsearch-powered course search.
