I shipped Cadivity.com’s production LMS end-to-end using Next.js, Prisma, and PostgreSQL, with a 20-model schema for payment and enrollment workflows.

I implemented authentication and role-based access control with Better Auth, and integrated Razorpay for secure, idempotent payments. I also strengthened API security with rate limiting, security headers, and request validation.

On MedFind, I built geospatial pharmacy search using PostGIS spatial indexes and radius-based queries so users can discover nearby pharmacies likely to carry a medicine. I’m pursuing a B.Tech in Information Technology at G.H. Raisoni College of Engineering.
