Back to original languageAbout Olivier
Freelance software architect & developer since 2015, I specialize in Python (FastAPI, Django, Wagtail) with over 20 years of IT experience, including 10 as a freelancer.
Currently, I am working full-time for a large group, but I remain available for one-off missions or technical support, particularly for VSEs/SMEs, cooperatives, or impact projects.
I am autonomous, rigorous, a good listener, and I deliver quickly.
My preferred stacks:
- Python (FastAPI, Django, Wagtail)
- PostgreSQL, Docker, Git
- Lightweight frontend (HTMX, Alpine.js, Tailwind)
- Local or cloud deployment
If you are looking for an experienced developer, capable of adapting, understanding quickly, and making things simple without sacrificing quality.
