Hello, again

I codify contracts between systems for a living, in Rust and Python; and once spent a decade chasing where the antimatter went.

Senior software engineer at PactFlow (SmartBear). I help lead the open source Pact Foundation and maintainpact-python; I also wrote tikz-feynman,rust-skiplist, and more.

Previously: data and cloud engineering at KPMG, and doctoral research in theoretical particle physics.

The year in code

4177 commits, 653 PRs, and 209 issues across 34 repositories.

Sep 2025 — Sep 2026
Most of what I make is open. The grid below is the truthful version of a résumé — public, dated, and dense in the parts where I was paying attention.
