01 About me

I'm a Mobile Application Engineer who turns product ideas and Figma frames into fast, reliable apps people enjoy using.

Over the past 3+ years I've engineered and shipped apps across healthcare, AI assistants, e-commerce, food delivery and real-time messaging. My focus is clean, testable, maintainable code: SOLID principles, Clean Architecture, and predictable state with BLoC and Cubit.

I care about the details users feel but rarely notice: a skeleton that loads in the right shape, a transition that explains where you came from, an error you can recover from.
