Scouting report

Cuban full-stack dev working the NestJS, Next.js and PostgreSQL/MongoDB stack

assessed from open-source footprint

Senior
60signal

Valter is a full-stack web developer fluent across Express, NestJS, React, Next.js, Node, MongoDB and PostgreSQL, primarily in TypeScript. He pulls a solid 9 total stars across an original-heavy 11-repo portfolio (YelpCamp among them) with a relatively low abandoned ratio. The polish signal is weak and nothing is currently deployed, but the modern Node/Nest backend focus and the comparatively strong star traction make this one of the more substantive profiles in the batch.
