I build software from the interface down to the infrastructure.

I started in frontend development, drawn to the part of software people actually see and touch. That obsession with the details never really went away — I still care about the animation that feels slightly off, the state that shouldn't desync, the layout that shouldn't jump, and the error that should fail gracefully.

But somewhere along the way, the boundary of "frontend" stopped making much sense to me.

Today I work across the stack because I like understanding the whole system. Interfaces, APIs, data models, architecture, infrastructure, deployment — and the decisions connecting all of them.

I work end to end by preference, not necessity.
