## Featured

- [RealPDF](https://realpdf.app): A full PDF editor that runs entirely in your browser: edit text in place, fill forms, convert Office files and sign with real certificates. Your documents never leave your device.

## Other works

- [Factory on Rails](https://github.com/shixzie/factory-on-rails): A software factory on Railway: describe a change, and a coding agent does the work in a sandbox and opens a pull request.
- [More on GitHub](https://github.com/shixzie?tab=repositories): Everything else I've open-sourced, experiments included.
