Scouting report

Dominican React and Node web developer with a high-volume repo history

assessed from open-source footprint

Senior

53signal

Winser is a web developer working across React, Node, Bootstrap and SQL/NoSQL, with 46 original repos and a couple deployed. Representative work includes a JavaScript loan calculator and Dr. Angela Yu's '100 Days of Python' challenge. The volume is large but retention is low: about 96% of repos are abandoned with only 4 total stars, so this reads as prolific, learning-heavy output rather than a maintained, high-impact body of work.
