Allen Joseph

Indie builder · Engineer · Remote

Solutions Engineer at Hypernative by day. On the side I build small, useful apps and ship them myself, from the first sketch to the App Store.

Before that I spent years in developer relations and blockchain engineering. I started coding at 13, I’m self-taught, and I’ve won 50+ hackathons along the way.
