Excellent work from Ronan, who in addition to being pleasant, was able to take over the application's code to fix a large number of bugs and allow us to quickly publish the application. Very involved, he carried out tasks beyond what was initially requested. Very pedagogical, he was able to explain the developments and options considered at each stage. We recommend Ronan, who did not count his hours, to allow us to release the app and provide the exact result we expected.
