Bluesky GitHub Discord Ko-fi
Hello, I’m Ryan!

I am an open source software developer and privacy advocate.

I make all sorts of software, including but not limited to websites, CLIs, Discord apps, and developer tooling. Lately, I’ve been writing a lot of projects with Rust, a language that I really enjoy using!

In the open source world, I contribute to a wide variety of projects; I also maintain a few miscellaneous Nixpkgs packages and several Catppuccin ports and userstyles.

I have been writing blog posts about software development, privacy, and whatever happens to strike my fancy since 2020. Feel free to peruse the archive!
