I'm a Full Stack Software Engineer

Hi, I’m Chitvan

I build production web apps end to end.

Full-stack engineer with 2.5+ years building responsive, production React/Next.js interfaces alongside Node.js/Express backends, REST APIs, and SQL/NoSQL databases (MongoDB, PostgreSQL, Prisma). Comfortable owning features end-to-end — implementing UI/UX designs into functional pages, writing clean and reusable code, designing server-side logic and APIs, and collaborating with designers, product managers, and engineers through Git-based code review.
