Full-Stack Developer
Freelance / Self-Employed (Remote)
Delivered 5+ production MERN applications end-to-end: frontend UI, Express.js REST APIs, MongoDB schema design, and Vercel deployment for startup clients.
Architected JWT-secured APIs with RBAC middleware, request validation, rate limiting, and centralized error handling in MVC structure.
Adopted TypeScript across React frontends and Node.js backends — strict typing eliminated runtime errors and improved maintainability.
Engineered GSAP timeline & ScrollTrigger systems — pinned sections, parallax, staggered reveals — achieving sub-2s TTI with 90+ Lighthouse scores.
Built server-side pagination, filtering, and search APIs for 300+ item product catalogs paired with optimized React query patterns.
