Scouting report
Go concurrency author — shipped gatekeeper locking library
assessed from open-source footprint
Derwin's standout is gatekeeper (16★, his top repo), a Go package for advanced concurrency control with selective unlocking, priority waiting, and timeouts — a non-trivial systems problem he wrote solo. An 11-year account with a real backend/Go lean, though recent output is light (19 commits last year) and nearly half his repos are abandoned. Best fit for a Go backend team that values low-level concurrency thinking over a flashy portfolio.
