What I'm looking for

I’m open to remote or relocation opportunities where I can build production Android applications, improve performance and user experience, and continue growing in Kotlin Multiplatform and cross-platform architecture.

At HandsApp, I build and improve B2C and B2B Android applications, integrating Jetpack Compose into legacy View-based products and accelerating UI feature development by 40%.

I’ve migrated payments from a native SDK to WebView, reducing APK size by 25%, improved onboarding completion from 62% to 84%, and increased crash-free users from 93% to 98% through systematic Firebase Crashlytics and AppMetrica analysis. I also use Firebase Analytics, Cloud Messaging, lazy loading, and deferred rendering to improve retention, performance, and production stability.

Across ride-hailing, restaurant, e-commerce, and athlete social-network applications, I work through the full development lifecycle and am growing in Kotlin Multiplatform, shared business logic, and cross-platform architecture. I’ve also mentored 20+ Android developers toward building production-ready applications.
