About
A passionate and self-driven app developer with a strong focus on building clean, responsive, and user-friendly mobile applications. I specialize in Flutter and Dart, and I love turning ideas into fully functional apps that create real value. I started my journey into development out of curiosity, and over time, it grew into a full-blown passion. From designing sleek UI/UX experiences to integrating complex APIs, I enjoy every step of the process. I've worked on e-commerce apps, chat applications, live streaming features, and more — always striving for performance, scalability, and a great user experience.
