About Alex Leung

Background

Current Work

Hi, I'm Alex. I'm a software engineer in San Francisco, currently working at OpenAI.

I keep a short Now page, with notes on what I'm focused on right now.

Engineering Work

My work has included embedded software for AR and AI glasses, backend and customer-facing systems for consumer finance, and early customer and operations software for home electrification.

Writing

I write about software systems, AI tools, technical books, experiments, and life outside work. You can find recent posts on the blog.

Away from the desk, I spend time reading, playing tennis, hiking, climbing, and hanging out with my cats.
