I collaborated with François on the development of a SaaS in Python/Django and React. He managed the entire project, from backend to frontend (which I designed via Lovable), including interfacing with external APIs and the complete deployment of the solution. Very autonomous, he writes clean and scalable code, communicates with clarity and precision, and works effectively asynchronously. His technical mastery and rigor truly made the difference. I recommend him without hesitation!
