Services / Fractional engineering
10–20 hours a week on retainer. I take direct ownership of complete features — design, build, ship, run — the way an in-house senior would, at roughly half the Western rate.
$4k–6.5k per month · 3-month minimum, monthly thereafter
Process
We scope the first month's outcomes on a call. The 3-month minimum starts only after we both confirm fit in writing.
Sprint planning Monday, demo Friday, async in between. I work CET hours daily — 4+ hours of live overlap with European teams, mornings with US East Coast.
I take complete features from design doc to production, participate in code review, and hold the architecture line as the codebase grows.
Each month closes with a written summary: what shipped, what's next, where the risks are. Continue, scale up, or wind down monthly after the minimum.

“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.
$4k–6.5k per month for 10–20 hrs/week — roughly $45–60/hr, where a comparable Western senior bills $100–150/hr. Three-month minimum, then monthly.
I work CET hours daily for QOOP — 4 hours of live overlap with London, 5+ with Berlin, 1–2 with US East Coast mornings. Async-first for everything else. I've never missed a standup.
Yes — your repo, your CI, your ticketing, your review process. I've shipped in everything from startup-chaotic to enterprise-formal, and I sign your NDA before seeing anything sensitive.
Short bursts are fine within a retainer month. If you consistently need more, that's a conversation about either a second retainer block or scoping a fixed-price project alongside it.
