About Léo

Freelance web developer, I design and develop reliable, high-performance web applications tailored to business needs.

With a BUT Informatique (Bac+3) degree, I quickly gained practical experience through several professional projects, notably during two internships in web development (France and Canada), followed by a year-long collaboration with a Canadian company. This experience allowed me to work on real projects, integrate into an existing team, and deliver features used in production.

I pay particular attention to code quality, maintainability, and understanding the business challenges behind each project.

Currently in a work-study program at Enedis, I continue to strengthen my skills in Symfony and best development practices in a professional context. In parallel, I am pursuing a Master's degree in Expert Fullstack Developer (Bac+5) at Ynov, which allows me to consolidate my skills and deepen my mastery of web technologies.

Autonomous, rigorous, and involved, I quickly adapt to projects and teams, with a simple goal: to propose effective and sustainable solutions.
