Scouting report

SuperRare CLI author — Haskell/PureScript, 115 merged PRs

assessed from open-source footprint

Staff
51signal

Charles's real signal lives in the SuperRare/RareProtocol ecosystem: 38 commits to superrare/rare-cli and 3 to rare-staking, backed by 115 merged PRs across 13 years on GitHub. His own repos are tiny (a PureScript GraphQL lib and a smart-contract bond platform, ~1★ each), so the draw is functional-programming depth and proven Web3 tooling work, not personal stars. Strong for a backend/systems team comfortable with Haskell.
