I employed the Model View ViewModel (MVVM) architectural pattern, combining Android ViewModel with Kotlin Coroutines and Flow to efficiently manage asynchronous tasks.With a Test-Driven Development (TDD) approach, I designed focused components with clear responsibilities, making maintenance and scalability easier. By leveraging dependency injection with Dagger Hilt, I was able to modularize the project, refactor legacy components, and improve the product’s scalability.In addition to my technical contributions, I played a key role in the recruitment process, conducting technical interviews and contributing to the professional growth of junior developers through focused training and mentorship.

I contributed to the inclusion of new vehicle types in the project, following the established 'State Machine' architecture pattern. I implemented different states for each vehicle, utilizing tracking techniques for reporting and enabling direct access to specific states via Deeplinking.I extracted the document validation feature into a separate module, which allowed the creation of a dedicated module for user data collection.Additionally, I worked on bug fixes and UI… Show more I contributed to the inclusion of new vehicle types in the project, following the established 'State Machine' architecture pattern.
