What I'm looking for

I am looking for a role that fosters innovation, collaboration, and growth, where I can leverage my mobile development expertise to create impactful applications.

I am a dynamic and results-driven Senior Mobile Application Developer with over 8 years of experience in delivering high-impact iOS and Android applications. My proficiency spans both cross-platform frameworks like React Native and Flutter, as well as native development using Swift and Kotlin. I have a strong expertise in scalable architecture patterns such as MVVM and BLoC, which allows me to build intuitive, user-centric interfaces that align with performance, accessibility, and modern design principles.

In my current role as Lead Mobile Developer at Tech Holding, I spearhead end-to-end mobile development for flagship applications, driving a 30% uplift in daily active users through innovative features and UX refinements. I mentor a team of six developers, conducting regular code reviews and workshops on state management and platform conventions. My commitment to optimizing app performance and collaborating closely with product, design, and engineering teams has resulted in significant improvements in user retention and app usability.
