Scouting report

Backend polyglot probing Go, Solidity and ML

assessed from open-source footprint

Senior
51signal

Charl shows the most technically ambitious range in the batch — Python, Go, Solidity and C# — with deliberate practice like a Go goroutines repo and a PUBG-placement Random Forest model, and the highest total stars here at 8 (max 2). It's still largely self-study: 15 original repos at 0.4 abandonment, 0 followers, no deployments and no external contributions. A strong learner for a backend or data role who hasn't yet shipped a marquee product.
