Author

This was built by me, Alicia Sykes (@lissy93 on GitHub). I'm an open source developer, passionate about Linux, security and the web.

I build free and open source software for the developers, sysadmins and sometimes humans. My objective is to build tools that respect a user's privacy and are accessible to everyone. I have a particular interest in security, Linux and self-hosting. But also just love to build things that are fun and (sometimes, maybe) useful.
