About
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.
The common thread
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.
The thread so far
One journey, connected threads.
Education, hands-on work and entrepreneurship often overlapped. They did not simply follow one another.
2022 — 2025

From writing code to building products.

Co-founder of Promesia
Building products for real use, from NeuroXTrain to BromeAI. Scoping, development, releases and early users. I sold all my shares in Promesia in January 2026.

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.
Build & deliver
Understand & connect
- Clarify the need and its users
- Prioritise scope and risks
- Design journeys and architecture
- Build interfaces, backend services and APIs
- Integrate useful AI when the need justifies it
- Deploy, maintain and evolve the product
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.
