Goals:Maintenance and development of functionalities for the Amil, Santander Odonto, and Santa Helena applications, both for Android and iOS.Challenges:After two months of working at the company, I solved the issue where the Debug configuration (the main code analysis tool) hadn't been functioning in the three Android applications for over 2 years. This correction allowed for greater efficiency, less time spent on developing new functionalities, and a significant improvement in error correction time for the entire mobile development team. Additionally, I contributed alongside the team to raise the rating in the Play Store from 3.2 to 4.0.I also developed a Kotlin library to add the Google Wallet health plan card to Xamarin Android.Main responsibilities:- Fixing errors- Developing new functionalities- Configuring Azure pipeline- Publishing to the App Store and Play Store- Generating application versions in AppCenter for testing- Code version control (Git)Technologies:Flutter, Native Xamarin for Android and iOS, Xamarin Forms, C#, Dart

Goals:Develop unit tests.Challenges:I have developed over 400 unit tests.Technologies:.Net Maui, C#, Xunit

Goals:Develop new functionalities in the Android application.Challenges:I designed and developed the white-label application model (the ability to create multiple applications using a standard template). This enables the company to generate new revenue by selling and customizing applications for its clients.Main responsibilities:- Architecture and development of the white-label application model- Development and architecture of a new application- Implementation of a new layout and addition of animations- Development of new functionalitiesTechnologies:Native Xamarin (Android), C#
