Android engineer focused on building reliable mobile products with Kotlin/Java, modern Android architecture, and a strong quality mindset.

I build native Android solutions with a practical engineering approach: clean architecture foundations, maintainable code, and production awareness.

My current professional focus is on:

• Kotlin and Java Android development
• Jetpack Compose and Jetpack libraries
• SDK integration and SDK-oriented mobile solutions
• Mobile app security and reverse-engineering awareness
• Wallet and payment/tokenization ecosystems
• QA mindset, troubleshooting, and production support

• Languages: Kotlin, Java
• Android: Jetpack Compose, Jetpack (Architecture Components), Android SDK
• Architecture: MVVM, Clean Architecture foundations, modular thinking
• Quality & Delivery: Fastlane, testing-oriented workflows, CI-friendly practices
• Backend/API integration: Retrofit, Firebase, REST APIs

• Native Android engineering (Kotlin/Java)
• Jetpack Compose UI development
• Mobile architecture and maintainable codebases
• SDK integration / SDK-centric development
• Mobile security foundations
• Payment and tokenization-oriented mobile flows
• Wallet/contactless ecosystem understanding
• Production support and issue troubleshooting

• Built and maintained Android solutions across Java and Kotlin codebases.
• Worked with modern Android patterns such as MVVM, Compose-first implementations, and architecture-focused projects.
• Hands-on experience with mobile reliability, delivery, and QA-oriented practices.
• Continuous learning across advanced Android topics including architecture, coroutines, dependency injection, and reverse engineering.
