Work with the same CTO of this YC-backed fintech app

Joe app let customers buy now and pay later on any store in Europe. It went through Y Combinator and reached acquisition โ€” the kind of outcome that proves I understand serious technical execution, speed, and operational pressure.

Tell me if this sounds like you.


Nothing built yet. But you've looked at Lovable. Scrolled freelancer sites full of profiles you can't tell apart. Asked an agency for a quote and watched the number come back at $40,000.


You don't want to code it yourself. You want someone with real experience โ€” not a stranger you have no way to evaluate. Without burning your budget. And someone who actually cares whether your project works.


Here's the hard truth: most products die because they never reach product-market fit. And you don't get there by guessing โ€” you get there by putting the right first version in front of real users, fast enough to learn something. Build the wrong first version and you've spent your budget buying an answer to a question nobody asked.


I'm Alassane Fall. I developed more than 30 projects and was founding engineer at Joe, a banking app accepted into Y Combinator and acquired for seven figures by a major french bank. Fundraising, the YC bar, a bank auditing our code line by line โ€” I've been through it.


Now you know why most projects fail.


Picture your day a year from now โ€” working on something you built, living from it, because the first version of your project was right.


So: continue with the options you already have? Or start with someone who's done this and come out the other side?

โœ“ Step 1

Plan your roadmap

We define the scope together โ€” what ships first, what waits, and what "done" looks like. No guessing, no scope creep once we start.

Build your project in 2 weeks

I combine senior engineering with AI-powered tools to build a scalable, production-ready MVP optimized for real user experience, not just a demo. You stay out of the day-to-day; I ship.

โœ“ Step 3

We iterate together

Your MVP goes live with analytics built in from day one so you see exactly how users behave, not just guess. I turn that signal into the next focused sprint.
