About Frédéric

I am an experienced fullstack developer.
My stack: React/Typescript/Next on the front-end and Node or Django/Python on the back-end.

I always look for the most efficient, maintainable, and sustainable solution.
I approach my work with a craftsman mindset: best practices, knowledge sharing, continuous learning.

Furthermore, I have extensive technical experience as a developer, Product Owner, Scrum Master, and project manager, which facilitates my communication with other project stakeholders.

I enjoy: coding, problem-solving, teaching, hunting tricky bugs, learning every day.

Do you have a project, need reinforcement, or occasional help?
I am available to discuss it.

Reviewed on 12/10/2025

I had the pleasure of working with Frédéric for several years. He demonstrates a high level of demand, particularly regarding code quality. Always available to help the rest of the team, he greatly facilitates collaboration with his good humor and positive energy. Frédéric brings valuable expertise in front-end development, with a particular sensitivity for accessibility. He never rests on his laurels: he constantly seeks to learn, improve, and consolidate his skills. You can entrust him with end-to-end features, from understanding the need to production deployment. He is also very versatile, capable of working on both front-end and back-end tasks. If an area for improvement were to be mentioned, it would be his occasional tendency to dive too quickly into very specific details, risking temporarily straying from the initial objective — but this also stems from his commitment to doing things well. I highly recommend Frédéric for his professionalism, his motivation, and his reliability.
