Mickaël joined the project a few weeks after development began. He integrated very well right away, proposing technical solutions while remaining open to the opinions of other team members. He is dedicated, motivated, and meticulous: he suggests creating tickets, and raises alerts if he notices malfunctions or missing elements. He is conscientious and rigorous in processing tickets: he understands the functional need, performs the necessary tests, and delivers high-quality work. Mickaël is a good communicator: he asks questions when necessary to ensure he has understood the need and clearly explains what he has done and the reasons for his choices. He is proactive in suggesting improvements for tickets, during refinements, or team meetings. He is proactive and does not hesitate to take ownership of a subject and see it through to completion, ensuring quality work. In summary, Mickaël is a very good developer who is pleasant to work with and contributes significantly to the product's success.

Collaborating with Mickaël was an exceptional experience for the Oscars team! His ability to communicate best development practices greatly contributed to the efficiency and quality of the product's code. By taking an interest in the business side, he was able to work autonomously on complex parts, always asking the right questions and proposing better solutions. I highly recommend Mickaël to any company looking for a developer with great technical expertise and a true team spirit.
