Oscar Hernandez

The most well-rounded early profile in this batch: six original repos spanning Java, HTML and C++, the broadest discipline mix here, and — uniquely — one verified external contribution, a commit to a stock-market anomaly-detection project. Stars and followers are still at zero and the body of work is small, so this is firmly junior. But a real (if single) merged contribution to someone else's repo, plus recent activity, sets this developer apart from peers whose work is entirely self-contained.
