With 10 years of experience in mobile technologies, I am dedicated to continuously improving my knowledge and staying abreast of the latest developments in the mobile world.
Specializing in Android, I have recently expanded my expertise to include iOS. Additionally, I possess proficiency in other programming languages, having utilized React Native and Flutter for mobile app development, as well as Kotlin Server and Node.js for backend development.
Currently, my focus is on maintaining and enhancing projects in my current role, while also managing a personal project that I made from scratch to manage features for my wedding, and published both Android and iOS apps in the stores, working with the api that I'm made using NodeJS.
One of my proudest achievements is the Zee.Now app, where I initiated development and continue to drive its evolution. With over 500,000 downloads, the app serves numerous cities in Brazil.

Tv Maze Client is a comprehensive app designed to search for and provide detailed information about TV series.
Originally, this app utilized XML for view creation and Koin for dependency injection. To enhance and modernize the app, I have recreated the views using Jetpack Compose and switched the dependency injection framework to Hilt. Rather than replacing the original implementation, I have maintained both versions, allowing users to choose and evaluate their preferred approach.
