Description

I help companies ship stable, scalable Android applications and solve critical mobile blockers fast.

I am a senior Android & Kotlin engineer with strong production experience in fintech and high-traffic mobile environments (1M+ users). I specialize in Kotlin, Jetpack Compose, Kotlin Multiplatform (KMP), and modern Android architecture.

My focus is not just writing code — but delivering reliable releases, improving stability, and accelerating product delivery.

I typically help with:

• Android app architecture & refactoring

• Kotlin Multiplatform setup & cross-platform integration

• Play Store publishing & release management

• Subscription & billing integration

• Performance optimization & crash reduction

• CI/CD & build configuration

• AI integrations (OpenAI, ML models, on-device inference)

I work independently or together with a small trusted team when the project scale requires it.

Available for short-term problem-solving or long-term part-time collaboration.

Let’s build something stable and production-ready.
