I've helped 25+ founders across UK, US, Ghana & Canada turn ideas into funded products. Clients backed by Google for Startups. One featured in Forbes.
I don't just write code—I make technical decisions that protect your runway. The architecture choices, the tech stack, the "build vs buy" calls. The stuff that matters when you're scaling or raising.
"I build like it's my own startup. Your success is my reputation."

How I work
Your idea deserves more than a slideshow.
From the founder's chair
I'm a CTO and co-founder myself. I think in trade-offs and runway, not just tickets and tasks.
89% of clients return
Most freelancers ship once and disappear. Mine come back for v2, v3, and refer their network.
AI in production, not demos
I integrate AI into systems serving real users at scale. I know exactly where it breaks.

Straight answers
Questions founders ask first.
Projects range from $15K to $50K depending on complexity. Fixed-price quotes after discovery call. No hourly billing, no surprises.
Most MVPs ship in 4-6 weeks. Simple apps: 2-3 weeks. Complex platforms: 8-12 weeks. Weekly demos so you see progress.
Most clients are pre-seed. Flexible milestone payments available. For exceptional projects, open to equity discussions.
100%. Full source code, complete GitHub access, deployment docs. It's yours to sell, license, or modify.
4+ hours daily overlap with US/UK/EU. Real-time Slack during overlap, async updates otherwise. Clients say I'm more responsive than local teams.
30 days of support included. After that: retainer for ongoing dev, or I help you hire and hand off properly.
