What I'm looking for

I’m looking for an Android-focused role where I can keep shipping production features, deepen my Kotlin expertise, and apply MVVM/clean architecture with Jetpack and Firebase—working in an Agile team with strong code review and continuous improvement.

I’m an Android developer with three years of experience, specializing in the Java ecosystem and actively transitioning to Kotlin. I own the full lifecycle of mobile app development and maintenance, with a strong focus on writing clean, scalable code and building intuitive user interfaces.

Recently, I led the technical adaptation of the Beam Home platform for Android Auto. This expansion improved accessibility for users by enabling safe, driver-friendly interaction with the interface while on the road.

I’m comfortable working across modern Android architecture and tooling: MVVM, SOLID principles, Jetpack (ViewModel, LiveData), and lifecycle management. I also build with robust backend services in Firebase (Authentication, Firestore, Cloud Storage, Cloud Messaging) and deliver networked features using Retrofit/OkHttp with GSON, while keeping quality high through agile (Scrum) processes and unit testing.
