ABOUT ME
$ who-am-i
I'm Sumit, a full-stack developer who likes turning messy, real-world problems into software that just works. Most of my experience comes from building for actual businesses — production websites, internal tools, and e-commerce platforms that people use every day, not just portfolio demos.
I work mainly across the MERN stack, with a habit of going end-to-end: database schema, API design, and the frontend that ties it together. Outside of client work, I'm usually deep in a side project, trying to push it from idea to something live.
