Recommendations
From LinkedIn recommendations by people I have worked with directly.
François is methodical and skilled. His attention to detail in coding best practices, coupled with his commitment to performance and maintainability, makes his work both reliable and future-proof. What sets him apart is his intuitive sense for UI/UX — an invaluable asset that not every frontend developer possesses. He consistently delivers interfaces that are visually appealing and thoughtfully designed.
I had the chance to work with François for a few years — a great experience. As a junior, he accompanied and supervised me during my first steps. François knows his stuff: undisputed master of React and Java. He is very professional and, beyond that, a great colleague and an asset to teams. Always ready to support and encourage colleagues in search of new knowledge.
François made my life as Product Manager so much easier. He comes to every meeting with ideas and concrete approaches. He works diligently and always puts UI/UX at the forefront. He provides great support to all members of the team and is constantly on hand to assist with any questions. I would highly recommend François to anybody looking for his skills.
Working with François was easy. Good listener, smart and fast to understand complex topics. He is efficient in designing, developing, testing and maintaining the exact solutions resulting from discussion, would it be UI or back end components. React Guru, he shares his passion and knowledge smoothly. I hope we'll collaborate on another mission soon!
François was my mentor during my internship at Paynovate, and his experience and expertise helped me take a significant step forward as a React developer. He made me aware of the standards and expectations of professional code, something I hadn't fully experienced before. Thanks to his guidance, I gained valuable insights into best practices that I still carry with me today. Beyond his technical skills, François is a great mentor, approachable, and an excellent teacher.
