Full-stack engineer
building AI-powered products_

I’m Rohit Kumar Rai — a product-minded developer shipping real-time SaaS, automation and AI agents. I like building the full slice: clean frontends, reliable backends and the pipelines that keep them honest.

Not your average
developer.

I like building things that actually ship. Real products, real users, real edge cases — not just clean repos on GitHub. Hashtric.com is a side project I grew into a live SaaS with subscription billing and AI pipelines running in production.

My edge is combining full-stack engineering with automation architecture. At Optymatch I built pipelines handling 500+ daily extractions at 99.8% reliability. At Bridge Healthcare I shipped HIPAA-aligned ETL that cut data retrieval time by 30%.

I’m in my B.Tech (AI & DS), currently looking for remote roles where I can own features end-to-end — from the first UI sketch through to the production deploy.

05/ why me

Hire me for the outcomes, not the stack.

A quick shortlist of what I bring to a team — and the impact metrics to back each one.

I ship. Fast.

6+ products shipped

Production SaaS with paying users, an acquired Chrome extension, multiple freelance launches. Track record > promises.

Product thinking

Founder mindset

I care about users, metrics and business outcomes — not just clean diffs. I design for conversion, retention and reliability.

End-to-end ownership

Full-stack + infra

Frontend, backend, AI pipelines, DevOps, billing. I can own a feature from whiteboard to production — and then operate it.

Performance-obsessed

Measured wins

Sub-2s previews, 40% latency cuts, 10k+ RPM pipelines. I measure, profile and only ship when the numbers tell a good story.
