PrinciplesHow I build

Reduce the attack surface

I design with fewer unnecessary features and connections to reduce risk.

Keep data close; collect less

The design policy is to be clear about storage and destinations and handle only necessary data. Check each app for implementation details.

Build quickly; verify with people

I aim for tools that are intuitive, easy to use, and fast.
