When I'm not shipping AI products, I'm running Honey Badgers Billiards Club — a competitive billiards community I founded in León, México. I designed the brand, built the website, and run the entire digital strategy.

12 active players. Competing nationally. Streaming live.

Because the best engineers I know always have something they build just for the love of it.

Most of my recent production work lives outside this GitHub (in private company repos and the live products linked above). The repos here are exploratory side projects and learning experiments.
