Services / MVP build
One senior engineer, fixed scope, fixed price. You get a production application — not a prototype — with weekly demos from day one and your core flow live by week two.
$12k–28k per project · 4–6 weeks
Process
A 15-minute call, then a written scope with locked price. What's in, what's out, what ships each week.
Repo, CI, production deployment, and auth land in week 1. The core user flow — the thing your product IS — demos in week 2.
Payments, admin, edge cases, polish. Weekly demo every Friday; you steer priorities between demos.
Custom domain, monitoring, documented architecture decisions. I stay on for 30 days post-launch at no extra cost.

“Working with Nayeem was a pleasure! Very good communication and he went above and beyond to make sure I'm very happy with the outcome! At the same time he went beyond the original project scope while still delivering faster and for less money than he estimated. If you have any doubts if you should hire him for your project: don't. You won't regret it.”

FAQ
Everything you need to trust the number before you act on it.
Next.js + TypeScript by default — the same stack I run in production for ImmoScout24-facing platforms. Postgres or MongoDB for data, Stripe for payments, deployed on Vercel or Cloudflare. If your team already has stack constraints, we scope around them.
Because scope is locked before I quote. The scope document lists exactly which flows ship; anything outside it is a paid change order. That discipline is what makes 4–6 weeks real instead of aspirational.
$12k–28k fixed, depending on scope — roughly half the $30k–70k a comparable US/EU agency quotes. 50% upfront, 50% at launch.
You own the code and the infrastructure outright — standard work-for-hire IP assignment. Most clients either take it in-house or continue with a fractional retainer for ongoing feature work.
