Full Stack Developer

Subham Kumar

I build modern web and mobile products with React, Next.js, React Native, and Node.js.

About

I turn product requirements into usable interfaces.

I am a full-stack developer with over 1.5 years of experience building production web and mobile applications across enterprise ERP, government workflows, education platforms, admin dashboards, and developer tools.

My strength is working close to the product surface: structuring messy flows, designing component systems, improving form experience, and keeping interfaces responsive, accessible, and easy to maintain.
