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.

I played a key role in migrating the codebase from Java to Kotlin, implementing the MVP architecture pattern and integrating dependency injection to enhance code maintainability and scalability. Additionally, I developed a library that streamlined the login process across other Android apps within the Somos Educação group, enabling users to access multiple apps with a single account.

Developed Android application for video streaming delivery, focusing on optimizing performance, ensuring a seamless user experience, and integrating robust streaming capabilities.

I configured and customized the Moodle LMS, implemented interactive courses using the SCORM format, and developed websites using WordPress as a CMS platform, creating custom themes and plugins to meet specific project needs.

I developed websites with intuitive administration panels, allowing clients to manage their own content autonomously and efficiently.
