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
5259 commits, 820 PRs, and 277 issues across 38 repositories.
Most of what I make is open. Each square below is one day of my GitHub contributions over the past year.
