Scouting report

Dominican full-stack dev building vanilla-JS clones and an Astro portfolio

assessed from open-source footprint

Staff

66signal

A Dominican developer with a 7.5-year account working JavaScript, TypeScript, Python and Astro, leaning frontend with backend and light DevOps. The 13 mostly-original repos include a from-scratch Excel clone in vanilla JS (my-excel-js) and an Astro portfolio, showing solid fundamentals without framework crutches. Traction is modest (5 total stars, max 1, 1 follower, 4 deployments) and the 'Senior' label isn't backed by standout open-source reach. A capable generalist whose vanilla-JS work demonstrates real craft on the basics.
