When the app broke for its users
I've been working with Anton for over a year now and as always he does a fantastic job. A few months back, we were having major problems with the code that was implemented by our first back-end developer. Users were seeing empty home feeds, they got logged out and couldn't get logged back in and a few other nightmares.
Anton helped us out and solved all of the problems we had. He also optimized many places of the app so that it could function smoother and faster.
Whoever hires Anton is lucky, I'll tell you that! Thanks so much for all of your help and hope we can work again in the near future. :)
