01 — About

I build products the way a small team wishes it could.

I'm Mohanraj Murugesan, a full-stack engineer working with founders and small teams across India and the diaspora. Most of my work starts the same way: someone has a product that needs to exist in six weeks and no one to own it.

So I own it. Frontend, mobile, API layer, payments, deployment — and the unglamorous parts in between, like getting an app through store review on the first submission. Three of the products I've shipped are live in production today; two more are in flight.

The numbers I care about are the ones a client can feel: ten thousand people using the thing, a page that loads thirty-five percent faster, a release that didn't get rejected.

What I build
→Next.js web apps, server-rendered and fast by default
→React Native apps for iOS and Android from one codebase
→Nest.js and Node APIs with Postgres behind them
→AI features on Gemini and Claude, wired into real products
→Payments with Razorpay and Stripe, live and reconciled
Availability
Taking on two to eight week engagements, remote-first. Currently two ongoing builds with room for one more.

Six builds. Six roles I held alone.

Featured case study
Homeyhuts

A stay-booking platform shipped as a pair: a Next.js web app and a React Native companion, both built and maintained solo. Search, listings, booking flow, Razorpay checkout and the whole shared state layer. The mobile app cleared app-store review on first submission.
