About Kevin

🎓 Computer Science Engineer graduated in 2005.
👨‍💻 Passionate about the PHPSymfonyframework with +10 years of experience (full stack developer, DevOps, complex task automation, project management, Agile methodology, team management...)
🚗 I am very **flexible**, ready to come work in (almost) all of France!
🇬🇧 Having worked in several countries, I am fluent inEnglishand can understand Spanish.
🔗 Symfony open sourcecontributor

I consider myself a helpful and enthusiastic person, driven by excellence, attentive to needs. In terms of work, I always adopt an efficient method, respecting good programming practices:
🔸Design patterns
🔸Application of the S.O.L.I.D. methodology as best as possible
🔸Simple, thoughtful design that leads to easy-to-read and test code.
🔸Research work on existing solutions to avoid 'reinventing the wheel'
🔸Knowledge transfer: comments in the code for business logic, user and technical specifications.
🔸Writing tests to avoid regressions, and ensuring better refactoring without changing behavior.
