Scouting report

Cuban mobile/web dev building an Astro portfolio and a Markdown editor

assessed from open-source footprint

Senior

65signal

Andy is a mobile and web developer working in TypeScript, Kotlin, Astro and Preact. His small set of 9 original repos is notably clean — low abandoned ratio (0.11) and high consistency (90) — with marky, a lightweight Markdown editor, as his most concrete original tool. Stars are modest (9 total, max 2). A compact, well-maintained early portfolio with a clear front-end-plus-mobile focus.
