Hello, again

I codify contracts between systems for a living, in Rust and Python. I once spent five years 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

5310 commits, 821 PRs, and 276 issues across 39 repositories.

Nov 2025 — Nov 2026
Most of what I make is open. Each square below is one day of my GitHub contributions over the past year.
