At Mentorchamp EdTech, I build scalable backend services and production web applications for an in-house RA panel and mobile-app trial experience. I develop secure, real-time trade-message workflows using Node.js, TypeScript, Express.js, MongoDB, Socket.IO, Redis, BullMQ, and Firebase Cloud Messaging.

I've also built 40+ APIs for an enterprise travel booking system and created ChatterBook, an LLM-powered PDF assistant. Previously at Testlify, I developed REST APIs, improved security through SAST/DAST fixes and vulnerability scans, and optimized MongoDB queries.
