Debasis Das

I’m a Full Stack Developer who builds production-grade SaaS platforms with end-to-end feature ownership—from architecture to deployment—using Next.js, TypeScript, Node.js, Express, and MongoDB. At OfSkool, I designed secure subscription workflows with payment gateway integration and asynchronous webhook verification, so transactions are processed reliably.

I also focus heavily on performance and security: I implemented Redis caching and MongoDB indexing to reduce API response times by ~35% on high-traffic endpoints, and I built JWT authentication, RBAC, and rate limiting to harden APIs and dashboard modules. On the frontend, I revamp experiences with modern React hooks and performance-optimized visuals using Three.js and GSAP, and I’ve strengthened my fundamentals through a React/Node.js REST APIs internship at Techzex.
