Scouting report

Veteran Scala/Java polyglot, but 88% of repos abandoned

assessed from open-source footprint

Senior
52signal

Jesús is a long-tenured (12.7-year) Puerto Rico polyglot across Scala, Java, C and JavaScript, with the batch's most-starred footprint (9 total) and quirky-but-real projects like Billboards-Scala, a weekly Hot-100 change-watcher and emailer. The big caveats are an 0.88 abandoned ratio and low 32 consistency, so the 'Staff' label outruns the sustained-delivery evidence. Genuinely interesting breadth for backend/systems roles, but probe recent focus and follow-through before leaning on the seniority.
