Example result after evaluation
Based on 7+ years of experience building apps that generate 30k€ MRR
I don't sell code.
I free entrepreneurs from tech.
7 years building apps. 30k€ MRR bootstrapped. 2 apps 4.9★ on stores.
I've made all the mistakes you're about to make.
"I lost 1 year coding features that don't generate revenue. Never again."
I've seen dozens of brilliant entrepreneurs stuck because of:
- ✗ Tech that holds back their vision
- ✗ Code that breaks under load
- ✗ Apps that never monetize
I bring entrepreneur ideas to life. Fast. Bug-free. Profitable.

MY APPS — PROOF IN PRODUCTION
No mockups. No 'work in progress'. Live apps generating passive cash.
EVOLUM
The meditation app that competes with Calm — without their €100M budget
Calm has a €100M budget. I found the angle they missed: hyper-personalized AI rituals that adapt daily to your mood and goals.
BEEDONE
The productivity app with retention above 75th percentile
Habitica has dozens of features. I built the essentials: 8 AI Coaches + AI Email/Notification Funnels + Gamification.
STRIVE
A complete social network built in 60 days
Feed, authentication, AI, paywall — everything needed for a social network. In 2 months.
SOCIALLY FOX
My first app. 0 experience. App Store process mastered in 1 month.
2015. Never coded. Never published an app.
4 apps. 7 years of experience. Code that runs passively.
And a publishing process mastered to the core.
Want the same for your idea?
Truth from the trenches.
They say it better than I do. 4 angles, 4 proofs.
"BeeDone is listed among the best AI productivity tools alongside Asana and Any.do."
"Youcef ships features in days, not weeks. When we have an idea on Monday, it's live on Friday. In 7 years of working together, he built technical foundations so solid that the app still runs today with 500€/mo costs. He's the CTO every entrepreneur should have."
"We built a complete social network in 60 days. Feed, auth, IA, paywall — everything. What blew me away: the architecture was clean from Day 1. No technical debt. Ready to scale. Youcef codes like a senior but ships like a hacker."
"Youcef gave me the opportunity to work on a feature. Communication was fluid. His expectations were clear. The goal was reached thanks to a simple and concise brief. I thank Youcef for his clarity of mind and trust."
They trusted me
