Scouting report

Cactus co-founder — 223 merged PRs across a polyglot stack

assessed from open-source footprint

Principal
60signal

James is the driving author behind his startup Cactus Ltd., with 223 merged PRs and heavy commits to private-feeling company repos (stamp-maker 42, csvprocessor 30, payment-spreader 8) in Java, Swift, Scala and Python. The signal is sustained founder-level output across many languages rather than public stars (his repos total just 1★, with 84% abandonment). Strong for a versatile senior generalist who builds and runs his own tooling.
