About Me

I’m a computer engineering student and software development intern focused on building clean, scalable mobile apps using Flutter. I enjoy turning ideas into real products and constantly improving my skills.

Currently, I'm diving deeper into State Management and UI patterns to deliver high-quality user experiences.
