I design, build, and deploy REST APIs and full-stack web apps for founders and product teams who need systems that work on day one and on day three-hundred. Node, NestJS, Express, TypeScript across the MERN and MEAN stacks; Python on hand for the AI work. PostgreSQL when it should be, MongoDB when it must be. Plan, prompt, review, test, then ship.
“ I build the kind of software you forget you're paying for: the one that doesn't page you on a Sunday, doesn't break in the demo, and doesn't need rewriting in six months.
An AI-powered medical-health band built on a Node service, with a Python AI layer alongside it: vitals tracked, phone data synced, life-saving updates written back to a physical NFC tag. Live at firstaidtag.ca.
Treat every byte on the tag like a promise: honest, current, and ready for the medic who reads it on the worst day.
on the design of the FirstAidTag sync layerFirstAidTag is a Node service with a Python AI layer that bridges three worlds: a React Native mobile client, the AI that reasons about a wearer's vitals, and a physical NFC tag any phone can read offline. The hard part is keeping all three in agreement, gracefully, when the network isn't.
Honest figures, by the practice's count. Fuller numbers on request.
FirstAidTag is the kind of system I take pleasure in shipping: hardware, software, and AI agreeing quietly so the person wearing it never has to think about any of it. I'd like to build the next one for you.
Start a similar projectThe thing I do most. NestJS or Express on Node + TypeScript, Postgres or Mongo, JWT auth, webhooks, third-party integrations. Documented, tested, and handed over.
GPT-backed automations, NLP on real product data, AI-assisted internal tools. Planned, prompted, reviewed, and shipped, not dropped in and forgotten.
When you need the API and a UI on top. Next.js or React on the front, the same careful engineering underneath, deployed to Vercel or whatever fits.
For teams that have outgrown the spreadsheet but don't fit off-the-shelf CRMs. Customer ledgers, automated invoicing, tax-compliant flows (FBR-ready), dashboards that surface the numbers you actually look at. Built around your process, not someone else's.
The practice is one engineer (me, Rohaan), currently working full-time as an Associate Software Engineer at Infinitiv.AI and taking on a small number of outside engagements each quarter. That keeps the work careful and the calendar honest.
I write in TypeScript and JavaScript on Node, reach for Python when AI work calls for it, commit to main through pull requests, and treat the README as part of the deliverable.
