What I'm looking for

I’m looking for an Android role where I can build and scale production apps end-to-end—owning architecture, shipping greenfield features, and collaborating closely with product and backend teams, with strong testing and reliable release processes.

I'm an Android Engineer with around 5 years of experience building native Android applications across streaming, e-commerce, and digital media products. I've contributed to products from early development through production release, collaborating on architecture decisions and delivering user-focused features.

Most recently, I've been developing Android and Android TV apps for a streaming platform from the ground up using Kotlin, Jetpack Compose, modularization, and Clean Architecture. My work includes video playback, Google IMA ads integration, analytics, performance improvements, and delivering reliable production-ready features.

Throughout my career, I've integrated REST APIs, improved application architecture and analytics, managed releases and production monitoring with Firebase Crashlytics, and worked closely with backend, product, QA, and design teams. I enjoy building high-quality mobile experiences with a strong focus on maintainability, performance, and user experience.
