About Isabelle

Fullstack developer Ruby on Rails / React, I help my clients in the design and evolution of reliable, performant and maintainable web applications.

👉 What I bring you:

A robust backend (Rails, PostgreSQL) and clear frontend interfaces (React).

Expertise in API design and third-party service integration.

Quality deliverables thanks to automated tests, attention to security and performance.

A pragmatic and user-oriented approach, from technical framing to production.

I work on the creation of new applications as well as on the maintenance and continuous improvement of existing solutions.
