Here are some projects I'm working on:
Debian
I've been an active Debian packager since 2015, and a verified uploader (DM) since 2018. Much of my work here relates to tools and themes for the Linux desktop.
I also maintain a personal repository shipping more niche apps and my default settings.
icoextract is a pure-Python icon extractor library and thumbnailer for Windows executables. It aims to be lightweight, portable (cross-platform), and fast on large files.
Variety is a featureful wallpaper download and manager, with support for numerous online sources (Unsplash, Wallhaven, etc.) and built-in effects/filters.
In collaboration with Peter Levi.
bookmarksync is a simple utility to manage and sync GTK+ and KDE bookmarks (i.e. favourite places). As seen on the Arch Linux Wiki!
Limnoria is a powerful, multi-purpose IRC bot written in Python. I work on the main project as well as a set of plugins, which talk to various services including OpenWeatherMap and Last.fm.
In collaboration with Val Lorentz and many others.
certpush is a simple tool to generate and deploy Let's Encrypt certificates on websites with multiple backends (GeoDNS, anycast, etc.). Under the hood, it uses rootless certbot with DNS verification.

I operate AS4242421080 within the dn42 experimental network; as of May 2022 it is a top 10 network by peer count, with ~12 PoPs and >100 active peers.
Much of my project focus here is leveraging automation (currently Ansible) to create a scalable and easy-to-maintain network.
