Available for serious product work

I'm Apratim Dutta — a React Native and full-stack developer in Kolkata.

I build production mobile apps, React web applications, APIs, and AI-assisted products for startups and fast-moving teams. I'm an Information Technology graduate of IIEST Shibpur with hands-on experience shipping to Google Play and the Apple App Store.

I turn ambitious ideas into dependable product experiences.

I'm a software engineer focused on mobile and web product development, currently working at SiteMaster across React Native and React features for real-time project updates, approvals, and operational workflows.

I do my best work when a team needs someone who can move between frontend execution, backend integration, and product thinking without losing attention to performance, polish, or delivery speed.
