About

I'm Matt Crockett. By day I lead engineering teams. Nights and weekends I build apps, games, and tools across whatever stack fits the problem: Kotlin Multiplatform, Flutter, TypeScript, Python, or something new.

Upstream Partners is the umbrella for all of it. Some projects are live in app stores, some are still in the workshop. The common thread is shipping real things to real users.
