Maxime YIP
I had the chance to work with Léo at WINAMAX, Léo is a great asset to work with in a team. I am always impress by his speed and the quality of his work. His expertise of React JS was a great help to sort out a lot of issues that I met. It's always a pleasure to work with Léo, he is very easy to work with and very passionate. I would definitively recommend Léo for any company who need someone qualified.

Léo was my final internship supervisor at WINAMAX, he gave me the knowledge that I was missing to become a Fullstack engineer. For 6 months, he was dedicated helping me going forward in the solution I was asked to develop, I could rely on Léo at anytime. He is one of the most professional person I ever met. Léo is result oriented and a very technical and responsible person that I would highly recommend to work with.
