About Clement

Creative above all, I have been in web development for about ten years.

Very curious, entrepreneurial, I enjoy designing products that address concrete problems.

Do you have ideas? Let's transform them together into a well-designed and user-friendly application.

I can assist you with many aspects of the stack:
- Frontend in CSS (especially tailwindCSS) and Javascript (React) / Svelte
- Backend in Ruby (on Rails)
- Databases with PostgreSQL
- Infrastructure with Docker
- Deployment on various environments
- CI / CD (Jenkins, Github actions)

I have worked for startups and scaleups, facing problems of growth, significant technical debt, and scaling.


I also have web design skills and am used to taking on projects from A to Z.
