How Iwork.

Most products break at the seams — where the interface meets the service, where the service meets the data, where the whole thing meets production. I work across those seams. I build systems that hold together end to end, and I stay with them until they ship.

Interfaces that survive production — React, Next.js, Flutter, React Native.

Underpressure.

Beyond product work, I keep the fundamentals sharp through contests and high-volume algorithm practice — decomposition, implementation speed, and holding a solution in your head under a clock.
