About Yohann

🤙 Welcome to you who pass by!

I am passionate about web development and everything related to well-thought-out software architecture.

With over 9 years of experience in web development, I have had the opportunity to work alongside startups, freelancers, and SMEs on demanding, tailor-made projects where code quality is not a luxury but a priority.

I place great importance on clean architecture, clean code, and good development practices (TDD, DDD, SOLID…). For me, a good project is a maintainable, testable, and scalable project, designed to last and adapt.

My preferred stack: React / Next.js on the frontend, Python (FastAPI, Django) on the backend, with a strong preference for tools that promote clarity, productivity, and robustness.

If you are looking for a rigorous, involved, and quality-oriented freelancer to accompany you on your web project, let's discuss it!
➡️ I am available for technical missions, redesigns, scaling, or development from scratch.
