I'm Kristofer. I build things. First, I built internet things for a few years. Then I built restaurants for quite a few years. Then, I went back to building internet things. And blockchain things.
I recently worked for Caffeine, doing evangelism and transitioning the organisation to an agentic future.
Before that, I spent some time with DFINITY, doing developer advocacy for the Internet Computer.
Further back, I used to work for Commons Stack, Token Engineering Commons and General Magic, building on Web3 platforms such as Hypercerts and the Ethereum Attestation Service (EAS).
I was the co-founder and lead developer of Praise, a community intelligence system that promotes active participation and collaboration through peer recognition and rewards.
