Concurrency, middleware, CQRS, production
Goroutine leaks, HTTP middleware, rate limiting, event sourcing — the patterns that hold up under load.

The track record.
Fourteen years writing production code, not slides. Lead technical developer at Decitre Interactive (Lyon, 2017-2019) on a B2B e-commerce catalogue of millions of references — search optimisation with Elasticsearch and SolR, Jenkins + Docker CI/CD.
Then lead dev on critical e-health applications at Teranga Software (EHPAD patient records, offline sync on tablets, Vue.js + Quasar), and backend architect on an AMF-regulated fintech at Goin Invest. Today: freelance, full-remote, with clients in France and French-speaking Switzerland.
I also train future developers (DWWM at OnlineFormaPro) and sit as a professional examiner for France Compétences (RNCP levels 5 and 6). Teaching a thing is the fastest way to find out whether you really understand it.
What I write about.
The blog is where the real experience goes — production problems, the fix, and why that fix. Two recurring pillars:
Coding with AI, for real
MCP servers, CLAUDE.md memory, agent orchestration, token costs — the honest practitioner view, not the hype.
Free interactive courses
I also build free courses to learn to code with AI — HTML to Go, with a runnable editor.
