Scouting report

Frontend craftsman with a shipped TypeScript utils library

assessed from open-source footprint

Principal
79signal

Ricardo is a long-tenured (11.8yr) React/Vue/TypeScript specialist who pairs design-system polish with real output — 188 commits last year and 219 merged PRs, verified as a major contributor. His public catalogue is modest in stars (ts-object-utils at 5★ is his most notable own work), so the appeal is consistent frontend execution and breadth rather than headline projects. A solid, dependable frontend hire.
