Maxence took over the ongoing mission with great professionalism and a great capacity for adaptation: quick takeover of Ruby on Rails code even though we didn't have specifications or developers for the handover. Maxence knows how to bridge the gap between technical language and commercial/simplified language so that we can understand what was going well and what wasn't. The mission was completed within the allotted and announced time. He also suggested new tools to implement to best secure our API. We plan to work with him again soon.
