Scouting report

Puerto Rican systems-leaning engineer behind the Kaimana Zero LED arcade controller

assessed from open-source footprint

Mid
45signal

A Puerto Rico–based developer working across systems, backend and data, whose standout original project is Kaimana Zero, a C++ rework of an arcade LED controller ("all the lights, none of the duplication") that earned 4 stars — his best signal. Other repos include a Raspberry Pi weather station. About half the repos are forks with a high abandoned ratio (0.67), so the embedded/hardware-tinkering work is the genuine through-line here.
