Curious about the need. Serious about the product.

I’m Tanguy. A full-stack and AI developer, with one foot in product and the other in building it.

I prefer understanding what gets in the way before deciding how to code it. I enjoy projects where we can discuss real usage, make clear choices and see an idea become a working tool.

A background in connecting the dots.

Based in Antibes, I work independently on products such as ORA and Log²EU, and am equally open to employment opportunities. Previously, I co-founded Promesia and contributed to BromeAI and NeuroXTrain. I sold my shares in January 2026. France, Switzerland or remote: the project and the team matter most.

That experience taught me to discuss a user’s need as readily as architecture, priorities or releases. Connecting those perspectives is what I aim to bring to every project.

One journey, connected threads.

Education, hands-on work and entrepreneurship often overlapped. They did not simply follow one another.

2020 — 2022

Understanding how things connect.

ServiceNow.
Business understanding, too.

At IN-IT, I worked on ServiceNow applications and processes: automation, integrations, JavaScript and access management. That experience informs how I build reliable products, without defining my entire practice.

ServiceNow · Certified System Administrator

Technology in its proper place.

I choose tools to fit the product, not the other way round. On ORA, T2 photos and LauDio, the code comes with decisions, tests and ongoing support.

And when I close the editor: sport, a guitar or a game of chess. Curiosity does not stop at code.

A project. A team. A conversation.

An independent engagement, an employment opportunity or a product to build together. Let’s discuss the need and what I can contribute.
