About

Hi, I'm Alex, a software engineer based in San Francisco. I work at OpenAI.

For a more current snapshot of what I'm focused on, I keep a short Now page.

My background spans embedded systems, distributed systems, and full-stack product engineering, with previous work across home electrification at Jetson, AR/AI glasses at Google, and consumer finance at Cash App.

I'm drawn to software products and systems that feel simple to use.

That often means working across boundaries: product definition, backend systems, data flows, infrastructure, frontend surfaces, and the engineering details that make the experience reliable.

I'm especially interested in problems where the shape is still being figured out: early ideas, product inflection points, and systems that need to grow without becoming harder to reason about.

Lately, I've been especially interested in AI product development: shaping useful product behavior, evaluating agent workflows, and keeping careful review in the loop.

I'm usually happiest in work where there are several plausible paths forward, and progress depends on taste, iteration, and good feedback.

I write notes on software, AI tools, and learning from small projects. If you want a better sense of how I think, start with my recent writing or get in touch here.

Outside of work, I spend time playing tennis, reading, hiking, rock climbing, and spending time with my cats.
