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
4785 commits, 744 PRs, and 274 issues across 37 repositories.
Most of what I make is open. Each square below is one day of my GitHub contributions over the past year.
