iCloud Drive was a deliberate shortcut to prove the CRDT converges across real devices before I solved networking. Proof done, I swapped the file-pusher for a real network. This is how outl now syncs every client peer-to-peer over QUIC, with no server and no Apple, and the parts of 'peer-to-peer' the brochures skip.

I had an exit and chose to be someone else's CTO for longer than I ran my own company. Founding was never about owning the company.

Open source activity in June 2026: PRs, reviews, issues, comments across multiple repositories.

The Kleppmann move-op paper proves convergence. It says nothing about markdown, two clients, iCloud Drive, vim, or a user hitting Enter while a peer writes. I built outl on top of that paper. Here is everything between the proof and a working sync.
