What I'm looking for

I seek senior mobile development roles where I can lead Android/Flutter projects, improve performance, mentor teams, and deliver scalable, user-centered apps.

I am a results-driven mobile app developer with over six years of experience building and maintaining Android and cross-platform applications using Kotlin and Flutter. I have led end-to-end development of production apps, architected scalable codebases using Bloc and Provider, integrated Firebase services, and improved app performance through focused optimizations.

I collaborate closely with UI/UX designers and cross-functional teams to deliver efficient, user-friendly mobile experiences, mentor junior developers, and deploy apps to stores with strong analytics and testing practices. My work has produced multiple high-rated Play Store apps and measurable performance and retention improvements.
