Titouan accompanied us for a week to improve our testing tooling, with an immediate impact. A former member of the Symfony Core Team, he has unparalleled PHP expertise, codes very effectively and knows how to popularize his choices and recommendations with clarity. He was able to quickly install our complex project in complete autonomy. In addition to being very competent, he is really nice. I recommend him with my eyes closed.
