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
4003 commits, 575 PRs, and 205 issues across 34 repositories.
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.
