What I'm looking for

I want a full-stack MERN role where I can build secure, scalable products, ship production-ready REST APIs and responsive UIs, and grow into cloud deployments with Docker and AWS.

I’m a motivated MERN Stack developer who builds production-ready full-stack web applications with clean, scalable, and well-documented code. In my internship, I developed full-stack MERN CRUD applications and integrated MongoDB schemas with Express.js REST APIs and React.js frontends, reducing average query response time by ~35% through targeted index optimization.

I deliver secure backend systems using Node.js and Express.js, implementing JWT authentication with access + refresh token rotation for stateless session management across protected routes. I also engineer responsive, mobile-first UI components with React.js and Tailwind CSS, and I’ve built 30+ REST API endpoints with production-seeded databases in Agile/Scrum environments—while currently exploring Docker and AWS EC2 for cloud deployment.
