What I'm looking for

I'm looking for a remote-first Android Developer role where I can contribute to product-focused teams building scalable, high-performance mobile apps or SDKs. I value clean architecture, performance optimization, and meaningful user impact. I’m especially excited to work with teams that prioritize ownership, innovation, and continuous learning.

Android Developer with 4+ years of experience building scalable Android applications, monetization systems, and high-performance SDK architectures. Currently working at GreedyGame, focusing on ad-tech infrastructure, offerwall systems, mediation pipelines, Play Integrity enforcement, and large-scale monetization optimization across production apps.

Experienced in Kotlin, OpenGL rendering, MediaCodec pipelines, server-driven UI, Firebase, and backend systems using Node.js. Worked on improving eCPM, ad fill rate, app performance, and SDK scalability across 50+ live integrations and 14+ production apps.

Strong background in Android architecture, monetization engineering, remote config systems, and performance optimization with hands-on experience in AdMob, AppLovin MAX, Unity Ads, Pangle, FAN, and Google Ad Manager.

Passionate about building scalable mobile systems, developer tooling, and high-impact consumer products.
