Product and Software engineer · Founding Engineer · Research and development - France

I used to write code. Now I build the systems that write it.

Lately, that means building products through AI development pipelines with coding best practices.

I'm a software engineer with over 10 years of experience. From idea to production, I enjoy building solutions that provide value. I leverage AI agents to accelerate the process while maintaining control and ensuring quality that meets product needs without blowing the token budget.

Selected work

Products that I have built or contributed to, including product conception, architecture, full-stack development and deployment. A selection from the past few years, shipped for teams across Europe and El Salvador.

AI Orchestration - Software factory — Orchestrates AI agents that take software from idea to production - specification, code, review, release - with a human in control at every gate.

Research and Development

Research and Development Engineer at INRIA, in the INOCS team, on EU Horizon and France ANR projects in operational research, optimization and simulation. I collaborate with the researchers: they develop the models, I turn those complex problems into user-friendly learning experiences - demonstrations and simulations that people outside the field can use.

The tools below are published by the INOCS team at Inria; the models are the work of the team's researchers.

SUM Open Data PlatformINRIA · EU Horizon
Where the SUM living-lab cities submit their policy measures and indicators, and anyone can browse, compare and analyse them. I build the public web application and the living-lab editor space.

Background

Before building products with small teams, I spent eight years inside some of Europe's largest retailers. That's where I learned how systems behave at scale, and how to keep them running.

Adeo2021–2024Identity and access for 30M+ users across 13 business units (Leroy Merlin, Technomat...). High availability APIs serving 500K+ requests a day, with on call production duty.
Auchan France2017–2018As Business Analyst, maintenance of core retail systems and ERPs for supermarket operations. Planning of legacy Gold ERP migration to company's information system.
Emphisphere (RFID Decathlon)2016–2017Full stack development and end to end testing of RFID solutions applied to logistics. Including RFID readers, web, mobile and Windows applications.
Decathlon2013–2016From engineering apprentice and developer to leading the technical customs domain as Business Analyst and project manager. Participating in strategic projects to migrate web applications migration and connection to SAP Customs module.

Working together

I keep room for project based or part-time/fractional consulting collaborations: product engineering conception, full stack development and deployment / AI development pipelines and orchestration / process automation with AI / agentic system architecture.

When a project requires a complementary expertise, I work with a trusted network of senior freelancers (product design, specialised engineering) so the right people with the right skills are on the team.

I have had the opportunity to work in English, French, and Spanish; I adapt to the language best suited to your team.
