Colfax.eth is the Co-founder & CEO of GitPOAP. He is a builder of all builders and he came initially from the EthStaker community.  He is passionate about Ethereum and open source. Colfax started giving away POAP tokens and found that it actually led to more contributions. Now, he has spun it up into an entire product, which makes it very easy to give out POAP tokens if you run an open-source project.
We have several big releases for earni.fi announced here. Earnifi now lets you save a GitHub username and search for GitPOAPs! Listen to the entire episode for those product announcements!
