Your web or mobile app, designed and delivered by a single point of contact
From the first screen to production: design, development, database, APIs and deployment. You get a clear process, full ownership, and one person to talk to from start to finish. Based in Lyon, I work with businesses and non-profits across the Lyon area and, remotely, all over France.

Custom iOS & Android mobile applications
An app that feels native, on iPhone and Android, from a single React Native / Expo codebase — not two separate builds, not two invoices.
Here’s what you get:
- An iOS and Android app published on the App Store and Google Play, ready for your users.
- A backend that powers it: accounts, data, business logic, push notifications.
- Over-the-air (OTA) updates to fix and improve without waiting again for store review.
- The screenshots, store listings and assets needed to publish, including in several languages.
I ran this exact process end to end, on my own, for Fusily — my recipe and meal-planning app, published on the App Store and Google Play.
Custom web & SaaS development
Fast, tailor-made websites and web apps, from a business website that converts to the full SaaS your customers use every day.
What I build:
- Business websites — fast, polished, well ranked.
- SaaS & business apps — accounts, subscriptions, dashboards, the logic at the heart of your business.
- Dashboards & back-offices — to steer your product or your team.
- Progressive Web Apps (PWA) — the feel of an app, straight from a browser.
High-traffic backends on platforms used by millions (Sketchfab, FAB / Epic Games); a business website delivered for the Eva Biezunski law firm.
What’s included, every time
Whatever the project, the whole chain is covered — no need to hire three providers or play conductor.
- 01
Polished interfaces (frontend)
Responsive, accessible and enjoyable, designed for your users, not recycled from a template.
- 02
Solid logic under the hood (backend)
APIs, business rules and a database ready to handle growth.
- 03
Live, and staying live (DevOps)
Deployment, hosting and automation, so your product runs without surprises.
How your project unfolds
A simple, predictable flow, with regular check-ins. At the end, you own the code and the infrastructure.
Scoping & needs
We clarify your goals, scope and priorities together.
Design
The screens and flows are designed before a single line of code.
Development
Your app is built in iterations, with regular check-ins.
Delivery & follow-up
Shipping to production, handover of access, and ongoing follow-up.
Clean, tested and documented code; maintenance after launch; no lock-in, no dependency.
How much does your project cost?
Every project is unique. Rather than a one-size-fits-all price, here’s how I estimate, so you have a clear picture before we even talk:
- Business website / PWA — from €1,500, a clear fixed price, scope defined upfront.
- Custom mobile or web app — estimated after a short, free scoping call, based on the features.
- Full SaaS — built in phases, to spread the investment and deliver value early.
The first conversation and the quote are free, no strings attached. You leave with an estimate, whether we work together or not.
Frequently asked questions
Who are your services for?
The services offered on this site are for businesses, non-profits and project owners acting in the course of their activity. I don’t take on private individuals as clients.
Do you only work in Lyon?
No. I’m based in Lyon: across the Lyon area, I’m happy to come to your offices for the key moments of the project. Anywhere else in France, I work remotely over video calls, with the same follow-up.
Do you work alone or in a team?
On my own, end to end — that’s the point: a single point of contact, no coordination on your plate.
What happens if you’re unavailable mid-project?
The code is versioned, tested and documented as we go, and hosted on your own infrastructure. At any point you — or another developer — can pick it up: nothing is locked in my head.
Who owns the code?
You do, entirely — code and infrastructure. No dependency, no lock-in.
Do you do both web and mobile?
Both, with the same care: React Native / Expo mobile apps and Django / Next.js web apps.
What happens after launch?
Handover of access, then maintenance and improvements over time if you want them.
How fast do you reply?
Usually within one business day of your message.
How much does a project cost?
A business website starts at €1,500, at a fixed price. A web or mobile app is estimated after a short, free scoping call, and a SaaS is built in phases. The quote is free, with no commitment.
