What I'm looking for

I seek senior Android roles building secure, scalable mobile apps (Kotlin/Compose) with strong CI/CD, performance focus, and mentoring opportunities in Agile teams.

I am a Senior Android Developer with 7 years of experience building high-performance, user-centric mobile applications using Kotlin, Java, Jetpack Compose, MVVM, and Clean Architecture. I have delivered scalable apps supporting 500K monthly active users and improved app startup time by 30% while reducing crash rates through targeted performance optimization.

I drive CI/CD automation with Jenkins, GitHub Actions, and Fastlane to cut deployment errors by 40% and mentor junior engineers through code reviews and workshops. I integrate RESTful APIs, GraphQL, WebSockets and Firebase services to create modular, maintainable, and secure mobile solutions.
