I help businesses and individuals design, build, and improve mobile apps that are reliable in production and easy to maintain. I develop native Android apps with Kotlin and Jetpack Compose, and native iOS apps with Swift and SwiftUI. I also work with Java codebases when you need to maintain a legacy app or modernize it incrementally to Kotlin. For the right projects, I use Kotlin Multiplatform to share business logic across iOS and Android while preserving a high-quality native user experience.

My work covers the full app lifecycle: feature planning, architecture, UI implementation, secure API integration, testing, performance tuning, release preparation, and post-launch improvements. I can step into inherited codebases to stabilize, modernize, and ship confidently. I have extensive experience with bug and crash fixes, new feature delivery, ongoing app maintenance, target SDK compliance, and App Store / Google Play compliance. I also handle API integrations, Firebase, third-party SDK integrations, Google Play Billing Library maintenance, Stripe monetization flows, ML Kit, and MVVM-based architecture best practices.

I’m a strong fit if you need more than just code. I can help define scope, prioritize the right features, and make practical technical decisions that reduce rework. Engagements can include new feature delivery, UI/UX modernization, store-readiness support, and ongoing iteration after launch.

If you need a mobile partner who combines product thinking with hands-on engineering, I’d be happy to discuss your goals and recommend a clear next step.
