Sumit Kumar

I am a Full Stack Developer with hands-on experience building responsive, scalable web applications using JavaScript, React, Node.js, MongoDB, and Next.js. I focus on clean UI, reusable components, and delivering features that genuinely help users.

I enjoy working with modern frontend tools and libraries such as Tailwind CSS, Framer Motion, GSAP, ShadCN UI and React Bits to craft smooth, animated interfaces and optimized user experiences. My projects emphasize mobile-first design and performance.

On the backend I design and implement REST APIs with Node.js and Express, using MongoDB (Mongoose) for data persistence and JWT/bcrypt for secure authentication. I apply best practices like validation, environment-based configuration and CORS handling.

I have completed multiple full-stack projects (fitness app, fintech SPA, Spotify frontend clone) that demonstrate end-to-end development, from UI components and animations to secure authentication and API design. I am motivated to join teams building user-focused web products where I can contribute and grow.
