Scouting report

Built ninjemail, a 275★ Python automation library

assessed from open-source footprint

Principal
84signal

David's standout is ninjemail (275★), a solo-authored Python library for automated email-account creation across major providers — a genuinely useful tool that drives nearly all of his 289 total stars. A Havana software engineer with a Backend/ML lean, he also shipped a Django real-time chat app. Caveat: only 2 commits in the last year and a 0.7 abandonment rate, so recent momentum looks light despite the strong single hit.
