Scouting report

Puerto Rico polyglot backend dev with functional-language breadth, low recent activity

assessed from open-source footprint

Mid
55signal

Long-tenured developer (13-year account, own domain) with unusual functional-language range, Elixir, Elm and Go alongside Java and Python. Strongest original project is an Elm music note-randomizer (5 stars); other surfaced work is starter templates. Recent activity is very low (2 commits last year) and 79% of repos are abandoned, so this is a broad, experimentation-driven portfolio that has cooled off rather than an actively shipping one.
