Datapult
Social image sharing on IPFS and Filecoin, from your iPhone. iOS app, website, and a Cloudflare backend, designed, built, and launched.

Datapult is the most complete product to come out of Team Zero: a free utility for sharing images on social media where the image itself lives on decentralized storage. Pick a photo, drop it in the box, and it's pinned to IPFS and the Filecoin network with a link you can post anywhere.
I designed, built, and shipped the whole thing: the iOS app, the website, and the API backend on Cloudflare. It was a first-of-its-kind product for the space and a good test of whether "decentralized" could be invisible to a normal person. Mostly, it could.
It's still live at datapult.site.
