What I'm looking for

I seek senior mobile engineering roles building native and cross-platform apps, leading teams in Agile environments, improving UX and performance, driving CI/CD and API integrations, and mentoring engineers in collaborative, product-focused companies.

I am a mobile developer with over eight years building native and cross-platform applications for Android and iOS. I focus on delivering seamless, scalable, and user-friendly experiences that meet business goals.

I have led development teams and managed full project lifecycles, launching production-ready apps to app stores while implementing advanced features like push notifications, background processing, offline sync, in-app purchases, and device integrations.

My technical breadth spans native (Java, Kotlin, Swift, Objective-C) and cross-platform frameworks (React Native, Flutter, Xamarin, Ionic), API integration (REST, GraphQL), CI/CD automation, and rigorous automated testing to improve release stability and performance.

I work well in Agile teams, mentor junior engineers, and prioritize accessibility, security, and measurable user engagement. I am looking to contribute to product-driven teams that value quality, mentorship, and continuous improvement.
