Scouting report

Dominican backend dev with .NET and Node API projects but stale repos

assessed from open-source footprint

Staff

67signal

Dominican backend-oriented developer working in JavaScript, TypeScript and C# (ASP.NET, Express, Sequelize) across 27 original, fork-free repos. He has the highest total star count in this batch (44, though spread thin at max 4) on projects like a .NET 6 PokedexApp and a web-voting SistemaElectoral. The caveats are real: zero deployed projects and a 0.93 abandonment ratio, so the work reads as a backlog of finished-and-shelved learning/coursework builds rather than maintained or live systems.
