Real screen from ioUman, a platform designed and built end to end.
Since 2013
Apps, websites, SaaS, AI
Nothing lost in translation
I keep the thread of the product from scoping to production, and I bring in AI only where the gain is measurable.
iOS and Android, native or cross-platform depending on the use. Testing on real devices and store submission included.
Websites, platforms and customer portals built to load fast, stay maintainable and grow with your business.
From MVP to a platform ready for its first customers, then ready to grow without starting over. Accounts, subscriptions, dashboards and admin back-office.
Connecting your tools to remove double entry and keep the data in sync.
Agents, workflows and generative AI wired straight into your processes.
Tell me your idea and I'll let you know whether, and how, I can build it.

UGAPDevelopment engagement on the online purchasing platform of France's public procurement agency.The scope is broad, several disciplines work at once, and team continuity matters more than cost.
More coordination interfaces, and a cost structure that also carries what is not development.
A multi-disciplinary team, parallel production capacity, and continuity that does not rest on one person.
The need is targeted, the engagement is short, and you already know what has to be done.
Quality depends heavily on selection and follow-up: you carry the management.
Fast sourcing on a precise need, with a contractual frame already in place and profiles available right away.
You are validating a hypothesis, tooling a simple, well-bounded process, and you want to move fast.
Limits show up around business logic, integrations and scale. Portability depends a lot on the tool you pick: check it before you commit, not after.
An idea tested in days, without writing code, using tools that do very well what they were made for.
An MVP, a SaaS, an app or an internal tool that needs clear technical ownership and a single point of contact.
A very large scope is split into phases or reinforced: this is not an agency, and the pace is set during scoping.
One point of contact, responsible for scoping, screens, code and production release, with the reinforcements it takes behind. That is what I do.
The last row is the one that matters: each of them is the right call somewhere.

| What you pay for | A team | The matchmaking | A subscription | The product |
| Code ownership | Depends on the contract | Depends on the contract | Depends on the export | Your repository |
| Right choice when | Several disciplines at once | Targeted need, short engagement | Prototype, bounded process | A product to own end to end |
40products shipped to production, from showcase sites to SaaS platforms.
Development assignments carried out inside these teams.
I worked inside large organisations, then built products end to end as a freelance, for teams in Canada, Sweden and New Zealand. I kept one simple rule from it: the structural decisions are made with the person who owns the business side, before they become expensive to change.
“The person who scopes your project is the one who architects it, builds it and ships it to production.”
Depending on your project and your ambition, I adapt to the right way of moving forward with you.
A ballpark figure in 30 seconds. Precise pricing comes after the scope is settled.

Across 40+ products shipped since 2013, a showcase website ships in 1 to 3 weeks and a mobile app or a SaaS in 6 to 12 weeks depending on scope. You get a firm timeline from the scoping stage, with a progress check-in every week.
I work at a fixed price on a written scope. The estimator above gives a first envelope; after scoping, you get the budget matching exactly the V1 we settled on, and any scope change is priced before it starts.
Yes, with clients all over France and internationally, by video and in writing. Everything is tracked in a shared space where you see progress in real time.
Going live isn't the end. After launch, you can keep the same point of contact for fixes, maintenance and improvements.
Always. The code is yours: clean, documented and hosted on your own account. No lock-in, no forced dependency.
To automate what costs you time: email sorting, content generation, order processing, customer support, data extraction. I only bring in AI where it delivers a real return on investment.
