Creator of Homebrew, the macOS package manager with the largest contributor base of any open-source project (a viral design that kept it running after he eventually left). Despite Homebrew's ubiquity he was never sustainably funded — GitHub Sponsors, Patreon and Ko-fi yielded only a few hundred dollars, not enough to live in the Bay Area — and cycled between maintaining the project full-time and taking day jobs. Now working on tea, a package manager plus proof-of-stake rewards system designed to fix the incentives for open source. Discussed the design of tea on the Stack Overflow Podcast.
