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). Open source contributor to pact-python,tikz-feynman, rust-skiplist, and more.

Previously: data and cloud engineering at KPMG, and a PhD in theoretical particle physics.

The year in code

3986 commits, 554 PRs, and 206 issues across 36 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.
