Caolan McMahon

Caolan McMahon earns a 94/99 Gitwork scout score with exceptional public open source reach and long-tenured maintainer credentials.

• High-impact public outcomes: 37,644 stars earned, including 28,152 on one repository, top tier for visibility on public GitHub.
• Sustained output and breadth: 18 years on GitHub, 78 public repos, 10 languages, with JavaScript primary and Scheme, Erlang, Python, and Rust also represented.
• Collaboration counts are modest in public data (13 pull requests, 1 code review, 4 issues), so pair star impact with a live look at current team workflow.
• All signals come from public GitHub activity only; 2,399 followers and 1,013 recorded contributions support strong community reach, not private employer work.

Strong fit for full-stack product engineering roles that value credible open source leadership, balanced long-term maintenance, and a controlled, steady working style built over many years. The 94 scout score is driven mainly by endurance and standout public outcomes rather than heavy recent commit volume (13 visible commits). Use interviews to confirm current delivery pace and day-to-day collaboration, since public review and PR counts are limited relative to overall footprint.
