Website, web or mobile app, business software: I turn your project into something that actually runs. Based in Marseille, working across France and beyond. Even if you know nothing about tech. Especially if you know nothing about tech.

(Method)
A clear framework, regular check-ins, and your project moving forward week after week. No jargon, no pointless meetings.
Every project has its own price, because every project has its own scope: a five-page brochure site and an app with a client area have nothing in common. To give you an order of magnitude: a brochure site starts at 1,500 euros, an app with a client area from 10,000 euros, business software from 15,000 euros. The method, on the other hand, never changes: we scope the need together, I write the specification, then I send you a detailed, line-by-line quote. You know exactly what you are paying for, and why, before you commit. The first conversation and the quote are free.
You can, and for some projects that is genuinely the right answer. What you don't see from inside the editor is everything else: GDPR and cookie compliance, technical SEO, load speed, security, backups, accessibility. That is what makes a site findable on Google and durable over time. An online builder gives you a shopfront. Custom development gives you a tool shaped around your business.
Expect 4 to 6 weeks for a brochure site, longer for an app or business software. The real variable is you: the faster you are on content and approvals, the faster it moves. The launch date is agreed with you at quote stage, and I stick to it.
I offer hosting and maintenance on a monthly plan: I monitor that everything runs, apply security updates, handle backups and step in if something breaks. You are never left alone with your site. And if you would rather take over, the code is yours and I hand it to you.

Three projects, three clients, three very different businesses. Here is what they say.

From idea to launch
Marseille · Remote across France
Maestro IA builds bespoke trips from your preferences, your budget and your constraints. The site had to make that promise obvious within seconds. I built the brand identity, the full website and the booking journey, from the first search to the return home. It has been live and running ever since.
Leafline lets farmers track crop health in real time, anticipate disease and pest outbreaks, and act before the harvest is affected. I developed the mobile app and created the full visual identity: turning a technically complex product into an interface you can pick up in the field with no training.
Tenentis Immo wanted to modernise its image and generate more qualified enquiries. I delivered the visual identity, the full website and the animations in three months. Result reported by the client: qualified enquiries up 20% over the three months following launch.
Self-initiated project. STOA translates Stoic wisdom into daily practice: a morning reflection, an evening journal, an AI philosopher to talk things through with. A way to explore how simple, calming and sustainable a daily routine can stay.
Self-initiated project. LIMINAL is a museum where each piece is not a fixed image but a living system, computed live on the GPU: flow fields, reaction-diffusion, Voronoï, volumetric nebulae. A playground for creative coding, art direction, and what a browser can do when you push it.
(In short)
No superlatives, no inflated numbers. Four things you can verify.
Thomas Mercier
Founder of Maestro IA
I came in with a complex product and a tight deadline. He delivered a mobile app and a visual identity that genuinely capture what Leafline is: precision, nature, innovation. He understood our agricultural world immediately, without us having to explain everything twice.
