pronounced LEV-un-DOS-key

I'm a very full stack software engineer: applied AI, infrastructure, back end, front end, UX, design and brand. I take AI products from zero to one, then build the teams that scale them.

Applied AI product maker, very full stack: the AI, the infrastructure, the back end, the front end, the UX, the design and the brand. I've taken products from zero to one, then built the teams that scaled them. On Deck grew to 450 people, Oak to 100.

I built this site by scraping and reconstructing my online presence from my own writing and projects, using AI. Read about the process.

Now

Before that, I was principal engineer at Translucent, director of product and platform at On Deck, head of engineering at Oak National Academy, and technical cofounder of Makeshift and Aframe. Full work history.
