Greetings! I am a Mobile App Developer with more than 11 years of experience building applications for iOS and Android. I specialize in React Native development, Flutter development, and native iOS development using Swift. I work with startups, founders, and companies that need reliable mobile software built for real users and real products. Over the years I have helped launch and improve many mobile apps, from early MVP products to large production applications used by thousands of users. My focus is building stable, scalable, and maintainable mobile applications that work smoothly on both iOS and Android. As a React Native developer and Flutter developer, I build cross platform mobile apps that share a strong codebase while still delivering a native user experience. When a project requires deeper platform control, I also develop native iOS apps using Swift, ensuring performance, reliability, and clean architecture. I often join projects where a company needs an experienced mobile developer to build an app from scratch, improve an existing mobile product, or refactor a growing codebase so it can scale properly.
