Description

Senior full-stack developer · 18 years of experience · PHP/Symfony · AI-augmented

I modernize impactful web applications — associations, SaaS publishers, startups, construction. My guiding principle: transforming legacy systems into solid and sustainable architectures (DDD, hexagonal, SOLID, TDD) with open-source tools.

What sets me apart today: I've integrated generative AI into the core of my development practice. I use Claude Code (Anthropic) daily as a technical co-pilot — not as a gimmick, but as a rigor multiplier: test generation, code review, assisted refactoring, security audits, Doctrine optimization, documentation. I've designed my own specialized agents tailored to each layer of a Symfony project (backend, Twig frontend, tests, DevOps, security). This mastery of AI allows me to deliver faster, with a test coverage and code quality that most teams only achieve with multiple people.

My career has forged a real adaptability: PHP 5 to 8.4, Symfony 2.8 to 7.x, various third-party APIs (DocuSign, AWS, Elasticsearch, Sentry…), complex legacy databases, contexts ranging from structured Scrum to associative shared governance. This adaptability comes from a deep understanding of architectures and businesses, not from a mere accumulation of frameworks.

Key skills:

· Backend: PHP 7.4→8.4, Symfony 5.4→7.x, Laravel, REST/GraphQL APIs, Doctrine, MariaDB, PostgreSQL, Redis, Elasticsearch

· Frontend: Vue.js, Web Components, TypeScript, Twig/Symfony UX, HTML5/CSS3

· Quality: PHPStan level 9, PHPUnit, Infection, Deptrac, TDD, AI-assisted review

· DevOps: Linux, Nginx, CI/CD, Sentry

· AI: Claude Code, specialized agents, prompt engineering, integrated AI workflows

What drives me: coding usefully, respecting people and nature. Free software, digital sobriety, ethical tools. Lead dev or contributor, I bring rigor, curiosity, and commitment.
