Ships products end to end

I'm a product-focused Full-Stack Engineer who owns features from architecture to production: UI, backend systems, REST/GraphQL APIs, database design, and deployment. I don't hand off work, I ship it.

Currently Co-Lead Engineer at GBCSGroup (SKYIT), guiding architecture decisions and reviewing peer PRs. In parallel, I run a one-person freelance practice delivering production systems for e-commerce and SaaS clients.

My stack is TypeScript-first by default: Zod for runtime safety, strict compiler settings everywhere, and code other engineers actually enjoy reading. I use AI-native tooling (Claude, Copilot, Cursor) daily to move faster without cutting corners.

Based in India, working remotely and comfortably flexible across EU and US timezones.

What I work with

TypeScript is the baseline. Everything else is colour-coded by what it does, like a real syntax theme.
