Hey 👋

I'm a software engineer based in the UK, mostly working with Ruby and Rails. I’ve spent over a decade working in the world of package management and software dependencies — building tools to make open source more understandable, discoverable, and sustainable.

These days I’m focused on Ecosyste.ms, a project that maps dependency networks across open-source ecosystems to identify the projects that really matter — the ones everything else relies on. It builds on ideas from Libraries.io, which I started and later sold to Tidelift, and takes the concept further with broader data coverage and deeper analysis.

I also created Octobox, which helps developers manage GitHub notifications, and 24 Pull Requests, an initiative to encourage open-source contributions during December.

Always happy to chat about open source, sustainability, or anything package-related. Check out my projects below or get in touch.
