About Me

As a senior mobile engineer with 5+ years of expertise in Flutter and Android, I build high-performance, responsive applications that deliver exceptional user experiences. My development process is accelerated by cutting-edge AI tools like Cursor and Gemini, enabling me to deliver robust, high-quality code with greater speed and efficiency.

I excel at translating complex design prototypes into pixel-perfect applications. Whether working independently or collaboratively, I am committed to building scalable, maintainable solutions that drive results.
