Building scalable web, mobile & GenAI applications.
Hi, I'm Hetu Patel. Full-Stack Developer specializing in MERN, Next.js, and React Native with workflow automation (n8n).
Full-Stack Engineer
System Architect
Algorithmic Mind
Tech Innovator
I care about owning a feature end-to-end — schema design, API contracts, and the interface people actually touch — and making sure it holds up once real users start relying on it.
From a cross-platform sports booking app (FirstBookIt) and an AI productivity platform (AvatarAI) to role-based access systems and real-time carbon-market infrastructure — I like building things that actually ship, not just demos.
