02 — About

How I work

Software engineer, ESPOCH graduate. I work end to end: understand the problem, model the data, write the API, build the interface, and leave the system deployed and observable.

I prefer simple, explicit systems over premature abstraction. Every technical decision has to fit in one sentence and survive production.
