TECHNICAL PORTFOLIO

Sergio Álvarez

;

Native Android developer (Kotlin / Java)

Keeping learning and every day more

With over three years of experience in Android development, I am an expert in Java and Kotlin, and have worked with essential frameworks such as Room, Retrofit2, and SharedPreferences. I follow the MVVM architecture and SOLID principles, using LiveData for efficient data flow. I’m familiar with the full release cycle on the Google Play Store, and my tech stack includes background services, Broadcast Receivers, and Coroutines, plus third-party tools like Firebase and Crashlytics. I am expanding my skills in Jetpack Compose, Dagger-Hilt and testing. I also have experience integrating machine learning models with Tensor Flow Lite and developing complex UIs. With my self-taught approach and adaptability, I’m ready to tackle Android development challenges of any scale..
