December 2019 - March 2020
Charmant app is internal app used by account managers of Charmant Charmant GmbH Europe. They focus on selling accessories such as eyewear. This app is used to input and track orders. I cleaned up all the warnings and potential errors, integrating Crashlytics, and also updating deprecated methods, so it will run smoothly on iOS 13 and later. I also created its documentation in Confluence.
