Freelancer profile translated to English.

Description

Backend developer for 15 years in various ecosystems (C++, nodeJS, Python, Ruby), now exclusively on Python/Django, to which I regularly contribute.

With extensive open-source contribution experience, I place a strong emphasis on code maintainability and reproducibility. Clear, commented, unambiguous code, adhering to best practices and conventions, covered by tests. PRs explain the reason for the change. Immediately understandable and maintainable. I consider myself a reliable and predictable collaborator.

Skills in evangelism (promoting a technology) and training (upskilling teams).

Also extensive experience in automated testing and CI/CD. Good knowledge of Kubernetes as well.

After several years as an employee, I am making the transition to freelancing.

On-site presence in Paris every day is possible.
