Scouting report
Dominican front-end-leaning JS engineer shipping React and Next.js clone apps
assessed from open-source footprint
Carlos is a JavaScript/TypeScript full-stack developer with a strong front-end lean (React, Next.js, Angular) and Node/Express/Nest on the backend. His portfolio is fully original (zero forks) and includes a Next.js/Express/MongoDB Threads social network and a Spotify clone with OAuth and playlist CRUD. Stars are low (max 3) and the abandoned ratio is high (~0.79), so much of the repo set reads as finished learning projects rather than maintained products.
