Software Development

Useful software is well-designed, well-developed… and well understood. I will assist you in creating or evolving your applications with rigor, pragmatism, and clarity.

From Prototype to Production Software

I can intervene at different maturity levels of your project, either alone or in collaboration with your existing teams or service providers:

• Technical and functional design
• Development of web applications or internal tools
• Code review and continuous improvement
• Implementation of best practices (testing, CI/CD, documentation)

A Craft Approach, But Not Improvised

I favor simple, documented choices that stand the test of time. Whether for a POC, an MVP, or a critical system, I emphasize readability, maintainability, and robustness.

“Jean-Louis took over a complex project without documentation and got it back on track in a few weeks. He was able to engage our developers with pedagogy.” — Claire, CIO at a large group

Clean, Tested, and Documented Deliverables
