Himanshu Rawat is a frontend systems engineer based in India with 4+ years shipping production SaaS products, startup MVPs, and internal platforms. React and TypeScript on the frontend, Node/Express/MongoDB on the backend — with UX ownership from the first Figma frame to the final deployment.
Most engineering hires force founders to coordinate a designer, a frontend dev, and a backend dev — three invoices, three handoffs, three points of failure. Himanshu covers that arc alone: UX design and IA in Figma, scalable React component systems, REST APIs, authentication, and deployment. One engineer, one invoice, one point of accountability.
Every build ships typed end-to-end with component architecture the next engineer can extend without a rewrite. Performance and accessibility are built in from the start — not retrofitted. Built for the next year of the product, not just the launch.
Currently building AI-native products end-to-end — an AI voice agent that handles L1 customer support and an AI-first social scheduler with an inline copilot. Both ship to production soon. Translation: the AI patterns founders read about on Twitter, I'm wiring up in real apps right now — model selection, prompt design, tool-calling, voice latency, eval loops. That experience lands in your build, not next quarter's blog post.
If this is the person you're looking for, about what you're building. I'll reply within 24 hours — no pitch, just a straight answer on whether I can help.

The builds I do best — and where I add the most leverage.
- Greenfield AI products from spec to live URL — model selection, prompt design, tool-calling, RAG, eval loops, deployment
- AI-native product features — voice agents, copilots, RAG systems, scheduled AI pipelines
- SaaS dashboards, admin panels, and internal tools built to scale with the product
- Startup MVPs covering the full arc from UX to deployed backend, one engineer
- Marketing and landing sites engineered for conversion and Core Web Vitals
- Figma to React conversion, including design systems and component libraries
- Performance rescues for slow, inaccessible, or brittle frontends rebuilt right
- End to end builds with UX ownership, React systems, REST APIs, auth, deployment

Scope + estimate in 48h
A written breakdown — what I'll ship, when, and what it costs. Fixed scope or weekly retainer. For AI features, scope includes model choice, eval criteria, and a failure-mode plan — not just "integrate OpenAI."

Weekly demos, daily PRs
You see progress every day in your repo. Demos every Friday. Nothing hidden until launch.

You own the code
Yours from day one. Documented, tested, easy for your team to take over. No lock-in.

AI Product Builder · Independent
- Building two AI-native products end-to-end — a voice agent for L1 customer support (OpenAI Realtime + Twilio + Postgres) and an AI-first social scheduler with an inline copilot (Next.js + OpenAI + Supabase).
- Architecture from spec to deployment: model selection, prompt design, tool-calling, RAG over user content, voice latency tuning, and eval loops.
- Both products ship to production soon — early access open on request.
- 2025 — Present
