About
I’m Rafal Litwin, a Full Stack MERN developer focused on building reliable, user-friendly web applications with React, Node.js, Express, and MongoDB. I enjoy turning requirements into responsive interfaces, well-structured APIs, and maintainable code by applying agile practices and modern JavaScript tooling.
Through hands-on work as a hybrid intern/full stack developer, I’ve contributed to React and Redux features, designed and tested REST APIs, supported MongoDB updates and query optimization, and helped with CI/CD and authentication flows using JWT and role-based access control. I also bring a test-driven mindset using tools like Jest and Postman, and I’m motivated by continuous learning and delivering performance improvements.
