Back to original languageAbout Gauthier
Senior Fullstack Developer, expert in PHP/Symfony, I work on SaaS projects and web applications with a strong product focus.
I support teams on:
- development of robust and maintainable PHP / Symfony applications
- design of REST APIs (API Platform, distributed architectures)
- performance optimization (caching, SQL queries, scalability)
- development of front-end interfaces (React) when necessary
- improvement of development practices (testing, CI/CD, Docker)
I have worked in various environments: web agency, large group (aeronautics) then high-growth FinTech, where I held a Lead Developer role with team management and architecture refactoring towards microservices.
Today as a freelancer, I primarily work as a senior PHP/Symfony developer on:
✔ PHP backend development
✔ Symfony development
✔ API design and evolution
✔ Fullstack development (React, Vue, JavaScript...)
✔ Performance and scalability optimization
✔ Refactoring and improvement of existing code
✔ SaaS and web product projects
