It was a great pleasure to work with Vincent.
We asked him to create builds for testing and submitting our application from Expo to the IOS and Android stores.
My developer and I were stuck for a long time because we couldn't understand why IOS wouldn't accept our certificates.
Vincent was patient and guided us throughout our implementation.
He is very comfortable with these information systems and was able to troubleshoot many of our problems.
It would be a pleasure to work with him again someday.
