Scouting report

Dominican Java/Spring full-stack developer with a broad but heavily abandoned history

assessed from open-source footprint

Mid
49signal

A full-stack developer from the Dominican Republic with a 13-year account and 38 original repos spanning Java, Spring Boot, React, Swift and Clojure, including the socialmint social network. The breadth is real, but the portfolio is almost entirely stale: a 0.97 abandoned ratio, only two commits in the last year, 44% forks across total repos and near-zero stars. Wide language exposure, but little recent or high-traction work to anchor on.
