Hi, I'm Raymond.

I'm a software engineer with over five years at Amazon Prime Video and B2B software companies, frontend to backend, and a little mobile. These days I build computer vision and tools for working with AI agents. Lately that means card games: models that find and name trading cards in gameplay video, measured carefully and shipped in the browser. It also means Vantle, an open-source experiment in checking what coding agents build.

I'm looking for a machine learning engineering role, ideally in computer vision. If your team builds models that have to work on messy real-world video, I'd like to hear from you.

I'm also starting a YouTube channel about engineering and the life around it, and building StackDepth in public.
