At GBJ Buzz Private Limited, I contribute to a 15-service NestJS backend and six Next.js applications for a live print-and-delivery platform. I integrated Razorpay with four payment methods and server-side order validation, fixing a flaw that allowed a 500 order to be paid for 1.

At YugaYatra Retail (OPC) Private Ltd., I engineered features for the HomiePG platform and implemented real-time booking updates, rent reminders, and tenant announcements. I also built projects including CoinFinex, a virtual stock trading platform with live WebSocket price updates, and IntelliText, an AI-powered text enhancement extension.
