About Joffrey

A product is not a pile of tickets. It's a vision that needs to stand on its own, from the first architectural diagram to production. That's exactly what I do: I design and deliver complete web & SaaS products. Not pieces of backend to be reassembled later, but the entire product, coherent, ready to run in real conditions. My foundation is solid Symfony engineering, the kind that makes an application age well instead of collapsing under the first load. On top of that, I build the rest: polished Vue.js interfaces, clean APIs, industrialized deployment. My real value isn't 'coding Symfony'. It's managing the entire chain without blind spots between backend, frontend, and production, where projects usually fall apart. A single point of contact, a single technical responsibility, much less back and forth. I use AI as an accelerator, not a crutch: it saves me time and expands my scope, but each deliverable still meets the same requirements for architecture, testing, and review. You keep the robustness, you gain the time. I work with companies that have real product challenges (ERP, back-office, SaaS platform, business application) and are looking for someone to take end-to-end technical responsibility. If that's you, let's talk.
