Hi, I'm Peter

I like making sites faster and cloud bills smaller.

About

I'm a senior software engineer based in Seattle, WA. Most of my career has been backend and infrastructure: distributed systems, query optimization, and slashing cloud spend. I care about the unshiny wins that move graphs in the right direction: building apps that feel instant, services that cost pennies to run, and systems that scale without drama. Outside work, I tinker with custom agent harnesses, eval loops, and a personal software factory.
