These days most of my open-source AI work and research happens at FWD AI, an indie lab focused on practical AI and local-first software.

15+ years of turning ideas into shipped products, built with the stack that fits the problem. AI writes a lot of my code now. I still own every line of it.

Local-first secrets manager. Passwords, passkeys, cards, IDs, SSH keys and .env files in one encrypted vault on your own devices. No account, no server, no subscription.
