I'm a Full Stack Developer specializing in the MERN stack (MongoDB, Express, React, Node.js). My core focus is building secure authentication and authorization systems for web applications — including JWT-based auth, OAuth2, session management, and role-based access control (RBAC). I also build complete e-commerce websites and online stores from scratch, with clean architecture and scalable code.
