GITHUB METRICS
AI Summary
Johan Haleby earns a 93 scout score with 16 years of sustained, high-impact public engineering work across Java and related stacks.
- Sustained output and endurance (95): 492 commits and 7,939 lifetime public contributions over 16 years on GitHub.
- High-impact outcomes (90): 3,877 stars earned, including 3,489 on one standout public repository.
- Collaboration (86): 179 pull requests, breadth across 9 languages, and a measured, deliberate working style reported from public activity.
Strong fit for full-stack product engineering roles where JVM depth (Java, Kotlin, Clojure) pairs with broader stack reach (JavaScript, Shell). Public history reads as a long-tenured, balanced maintainer with steady high output and community-visible results earned over years, not a short burst. Review public repositories directly before hiring, since this brief is based on public GitHub output only.
