About01
Useful products. Clean foundations. Room to grow.
I'm a Flutter developer focused on building high-performing applications with scalable architecture and a clear, intuitive experience.
Over the past two years, I have developed and maintained Flutter products in a professional environment—from shipping features and integrating REST APIs and Firebase to deploying across Android, iOS, Windows, macOS, and web.
I care about the details behind the interface: structured code, maintainable state, dependable integrations, and products that remain easy to improve as they evolve.
