Scouting report

Puerto Rican developer with all-original Python and Java coursework projects

assessed from open-source footprint

Senior
40signal

Rey is a Puerto Rico developer interested in data/ML and backend, working in Python, JavaScript and Java. Notably every repo is original (0 fork ratio), including a Java InstantMessenger socket project and a simple JavaScript todo app, though these read as academic/data-communications coursework. With one star, six followers and a 0.71 abandoned ratio, it's an early-stage portfolio, but credit for building rather than forking.
