Scouting report

Compiler-builder — wrote a full HULK language interpreter in C#

assessed from open-source footprint

Senior
56signal

Ernesto, a CS student at the University of Havana, is the most active coder here with 138 commits last year and a from-scratch HULK language interpreter (C#) as his flagship. He's a pure solo author with modest stars (max 1★) and no external contributions, but the consistency (85) and language depth across C#, C++, Python and Kotlin signal real fundamentals. A strong junior/mid backend or systems hire who clearly enjoys hard problems.
