+ AI CTO AGENT — MOBILE APP
Your app ships a new version.
Every two weeks.
You ask. It gets designed, built, tested, fixed. You check it on your phone, you approve, it's live on the App Store and Google Play.
No team. No agency. Nobody to chase.
TWO RELEASES A MONTH, ZERO HIRES
Graduate engineer, French engineering school (EPITA, Paris), 10 years of engineering including 7 on production apps — Renault Digital, Groupe La Poste, Pierre & Vacances. This setup runs on my own apps first.
+ THE CYCLE
Six steps. You do two.
Here's what happens between “we should be able to filter by date” and the version installed on your users' phones.
- 01
You ask
One message. In plain words, like to a human.
- 02
It designs the screen
Layout and flow, submitted before any code.
- 03
It builds
iOS and Android at once, one codebase.
- 04
It tests and fixes
It loops until nothing is red.
- 05
You approve
On your phone, the real app. Yes or no.
- 06
It ships
App Store and Play Store, changelog included.
Your time on this cycle: two messages and five minutes on your phone.
+ THE OFFER, IN ONE SENTENCE
- I help
- founders with an app on the stores, or an app to ship, and no engineering team
- who have the problem of
- ~€15,000/month in salaries to hold a mobile product, even with the whole team part-time — so nobody holds it: the next version waits six months, and the payment bug waits nine days
- to
- two versions published a month on the App Store and Google Play, approved from your phone
- with
- an AI agent that designs, builds, tests and ships — operated by me, one point of contact
- in
- a 4-week groundwork phase — by the end, the app is live
- for
- €15,000 groundwork then €3,000/month, against €15,000 in salaries: five times less for a product that actually moves
- without
- no mobile team to hire, no sprint to arbitrate, no ticket to write — and never a terminal to open
- otherwise
- until the app is live on both stores, the monthly doesn't start — you pay for a shipped product, not for a build in progress
To say no, you have to say: « €3,000 a month is too expensive for a team I price myself at €15,000. »
+ WHAT CHANGES
Same bug. Two worlds.

+ WHAT IT COSTS YOU TODAY
You're not looking for an engineering team. You're looking for your app to move.
Holding an app on both stores takes five roles. None of them full-time — but all five. Here's what that costs part-time, every month, before you even know whether they deliver.
Product owner
Decides what to build, writes it down, arbitrates.
~€2,500/mo
UI / UX designer
Draws the screens before anyone codes them.
~€2,200/mo
Mid-level mobile developer
Builds the features on iOS and Android.
~€5,500/mo
Junior backend developer
The API, the database, the notifications going out.
~€2,500/mo
QA / tester
Checks the new version didn't break the old one.
~€2,300/mo
The total, every month — five part-time roles
~€15,000
Here, you pay €3,000. All five roles are covered.
And that total assumes they're good, that they stay, and that someone coordinates them. In a small company, in practice, you hire one or two of them — and the next version waits six months, or never ships.
+ WHAT IT DOES
Six things. Every day.
Each one already runs on my own apps, published and paying. What I install for you is the same setup, on your product.
It builds the features
You describe the need in plain words. It turns that into a screen, splits it into tasks, builds it, and submits the result.
- From need to screen, no spec document
- iOS and Android from one codebase
- Nothing merges without review
It tests before you do
Two nets. A fast pass answering “does it even start”. Then a full pass replaying the user journeys one by one, looping until nothing is red.
- Fast pass in 5 minutes
- 30 to 50 journeys replayed before release
- It fixes what it breaks, on its own
It ships when you approve
Version number, build, signing, changelog, submission, Apple review tracking. One command, both stores. Nothing goes out without your green light.
- App Store and Play Store
- TestFlight for your testers
- Your green light, always
It watches and repairs
When a release fails at three in the morning, it reads the error, fixes it and re-runs. You find out in the morning, already repaired.
- Releases monitored
- Production fixes within 24h
- You're informed, not disturbed
It keeps the code from rotting
One feature combed through every week against a reference architecture. That's what makes month twelve as fast as month one.
- One architecture review a week
- Dependencies and alerts tracked
- Risky areas flagged before release
It works with humans
Got a designer, an illustrator, a developer friend? It takes their mockups, implements them, and submits the result back for review.
- Mockups picked up as-is
- Your own developer can review every change
- You can add people whenever you want
+ WHY THERE'S A GROUNDWORK PHASE
Autonomy isn't declared. It's built.
Everyone has an agent that writes code. An agent that ships to the App Store without breaking your customers' app rests on three things. The four weeks of groundwork are for putting them in place.
The architecture
Code filed the same way every time. That's what lets you touch one screen without breaking three others.
The test harness
The journeys that make you money, replayed automatically. Without it, nobody can ship without you.
The release chain
Build, signing, stores: one command. Without it, every release turns back into an engineer's evening.
→ From there, a version can ship without you opening a laptop.
The groundwork isn't an entry fee: it's the core of your app, built and published. You walk away with a running app even if you stop the month after.
+ THE PRICE
Three lines. Published.
You know before we start what a normal month costs and what a heavy month costs.
The groundwork
once, 4 weeks
€15,000
Your app's essential feature — not the whole app, the one that creates the value. By the end, it's on the stores and the machine can run.
- The feature that creates the value, designed and built
- iOS + Android from one codebase
- Accounts, payments, notifications, analytics
- App Store and Play Store accounts in your name
- The test harness
- The one-command release chain
- Your product's rules, written down
The monthly
your app keeps moving
€3,000/mo
Two releases published a month, without you having to ask twice. No lock-in, 30 days' notice.
- 2 versions published on both stores
- ~6 features or fixes delivered
- Full regression pass before every release
- Production fixes within 24h, off the meter
- One architecture review a week
- One 30-minute call a week
- One readable monthly report
The meter
beyond the quota
per unit
A launch, a big feature, a second product. You know what it costs before you ask for it.
- Extra feature — €490
- Extra published release — €150
- Second app on the same subscription — +€1,900/mo
- No “unlimited”: that's a lie on a delay
What you're comparing against
Compare the groundwork to an agency quote for the same feature: €35,000 to €60,000, and four to six months. Compare the monthly to the team you'd have to hold — five roles, part-time each: about €15,000 a month. Take the salaries you'd pay and do the maths yourself.
And so there's no misunderstanding: the €3,000 is my price, not an infrastructure cost. What the machine costs me to run is my problem, not a line on your invoice. You're not buying a script that gets handed over and left with you — I operate it. If a release breaks at three in the morning, it's my night, not your budget.

+ WHAT STAYS YOURS
You don't rent your own product.
The obvious risk with an offer like this is becoming dependent. Here are the guardrails.
The code is yours
On your account, from day one. Not a copy handed over at the end: the repository is in your name while we work inside it.
The store accounts are in your name
App Store Connect, Google Play, the signing keys, the payment access. I work inside them, I don't own them.
Anyone can take it over
Standard architecture, documented. A Flutter developer you hire tomorrow picks it up without me. You're not stuck with anyone.
You approve, and everything is logged
No version goes out without your green light. Every release is dated, with what changed and why.
Truth from the trenches.
They say it better than I do. 4 angles, 4 proofs.
"Youcef held the Flutter lead dev role within the Renault teams, and also onboarded Flutter devs in Brazil on an international project. Reliable and invested, he takes full ownership of the responsibilities he's given. I recommend Youcef for his professionalism and mindset."
"Youcef gave me the opportunity to work on an alarm feature for his app Evolum. 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 his trust. I can't wait to work with him and Evolum again someday."
"I worked with Youssef for two years — very dynamic, an excellent developer, technically solid and always involved in what he does. He knows how to listen, share and move the team forward simply. Always motivated, he brings real positive energy and good vibes that make the difference day to day. I recommend Youssef without hesitation and would be glad to work with him again."
"Quickest learners I have seen and always up to the work which was assigned to him. I have worked directly with him and Youcef was always ready for helping out anytime. Very cool, calm and composed when it comes to issues debugging and excellent root cause analysis skill. He has shown immense growth now and working with probably one of the best technologies."
"Youcef is a passionate developer with great potential. I had the chance to work with him on a project using React Native, among other technologies, and he showed a real ability to adapt and to bring ideas forward."
"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."
"I had the chance to work with Youcef for over 5 years, and I was impressed by his skills. He brought my craziest ideas to life — ones that demanded real technical feats. He is precise, rigorous, fast and an extremely good listener. It was a pleasure working with him on this project. I won't hesitate to call on his services again!"
"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."
+ THE OBJECTIONS
What you're already wondering.
An AI shipping to the App Store on its own — won't it break my app?
It never ships on its own: it ships once you've approved. And between the code and your phone there's a fast pass and then a full pass replaying 30 to 50 journeys. If a single one is red, nothing goes out. It's the exact opposite of a developer in a hurry on a Friday night.
How is this different from your fixed-price mobile app offer?
The fixed price delivers an app and stops. Here, the groundwork delivers the core of the app — then your product keeps moving every month, without you having to spin up a project each time. If you just want an app and nothing after, take the fixed price. I'll tell you so on the call.
What if I already have an app?
Then we don't start from zero. The groundwork goes into laying the three rails on your existing code — architecture, tests, release chain — and it costs less, because there's less to build. We price that on the call, on your repository.
What's still on me?
Three things. The product — it's your business, you know what to build, I don't. Approving each release. And the developer accounts, in your name, paid by you: that's what guarantees you keep everything.
Can I keep my designer?
Yes, and it's better that way. They do the mockups, those get implemented, they review the result. Same if you already have a developer: they can read every change before it goes out.
And if it doesn't suit me?
The monthly has no lock-in, with 30 days' notice. You keep the code, the store accounts, the live app and its users. I'd rather you leave with everything than stay because you're stuck.
+ NEXT
Tell me about your app. I'll tell you what ships in week 1.
Thirty minutes, no pitch deck. We look at your product, at what's blocked today, and I'll tell you honestly whether this is the right offer for you.
