Summary

Utilizing Kotlin, Swift, and Dart, the board's idea was to implement a set of skills for each software engineer so that all developers would know both the native languages (Kotlin and Swift) and the hybrid framework (Flutter), as both platforms connect modularly with Flutter. Thus, an app for Android and iOS was developed using native languages and Flutter, combined with the MVVM design pattern for the purpose of managing a fintech via a REST API to connect services.

Some of the main tools used were:

• Live Data;

• Dependency injection with Koin;

• Coroutines;

• View Binding and Data Binding;

• Clean Architecture using SOLID and KISS principles;

• Modularization between libraries;

• Deep links;

• UI testing with Espresso and Robolectric;

• Unit testing with JUnit 4 and 5, with mocking via Mockito and Mockk.

Auxiliary tools such as Jira, Git, and Firebase (Auth, A/B Testing, Firestore, Analytics, and Crashlytics) were also utilized.

Journey

Initially, I was allocated to the onboarding squad, where I stayed for just under a year. There, we were able to implement very interesting new features such as the new proof-of-life system and the new Will registration process. I was also able to mitigate the main cause of bugs in the Android onboarding squad—nested inheritances—and create a smoother registration experience, which earned Will Bank the ranking of the second-best onboarding by NPS, with a score of 6.88, second only to Nubank with 7.5 (source: https://marllons.dev/media/ranking-de-onboarding-2022.pdf, page 78). Shortly after, I was reallocated to the user acquisition via invitation squad, where I implemented the invitation system via deep links and stayed for about 3 months. After that, I was moved to the cards squad, where I was responsible for the app's gamification flow associated with cards.
