Lead Flutter Developer

• Apr 2020 - Jun 2021

Lead Developer of the Flutter Web team (7 developers) with a very close relationship with the different teams - Ops, Backend, Design and Business. Other than planning the architecture, coding standards and documentation for the Web Application, there was a heavy focus on R&D: - Creating a Splash Screen for Flutter Web Apps; - Using Rust and WASM as a solution to improve the performance of the application when heavy computation was needed; - Creating and managing JS libraries that needed to be integrated, such as Stripe and Google Maps, whose official libraries were not created at the time; - Using gRPC in Web - Using OAuth2 in Flutter Web Show less

Flutter Developer

• Dec 2018 - Apr 2020

At Ianum, I was tasked with creating, testing and maintaining the Ianum Flutter App. This was an Identity Provider application that could allow users to login into a platform using a QR Code. As the sole developer, I managed the app architecture, with Clean Architecture and Vanilla Bloc as a State Management solution, and created the testing strategy, with integration, unit and widget tests. It was also explored the possibility of splitting the app into several different libraries so that it would have an easier git branch management and a better separation of concerns. During the development, there was R&D done in: - Porting the Bouncy Castle from Java and using isolates to optimize the creation of RSA keys; - Using Add-To-App to create a native library that could be used by other applications; - Optimization of different QR Code readers so that we could support older versions of Android. This led to a complete refactor of an existing QR Code scanner with the inclusion and handling of a different Android library. Show less
