33 open-source tools

Linux desktop · Wayland · Omarchy

I build open-source tools for the Linux desktop, mostly around Wayland, Hyprland, and Omarchy. My paid work is web development in .NET and JavaScript.

Most of these started as fixes for things that bugged me in my own workflow, so they tend to be local-first and keyboard-friendly. My main project at the moment is Wayscriber, a ZoomIt-style screen annotation tool for Linux and Wayland.

How I build

Native where it matters.I use Rust, C++, QML, or .NET when a tool needs to be fast and fit the platform.

Local first.Private data and everyday workflows should stay on the machine whenever possible.

Keyboard friendly.Shortcuts for the things you do all day, without hiding how anything works.

Built from real needs.Every tool here started as a fix for something that kept getting in my way.

Work with me say hi

I do the same work for clients: .NET architecture, AI integrations, and rebuilds of systems that have outgrown their design.
