Scouting report

Dominican full-stack and mobile dev working across Kotlin, TypeScript, and Python

assessed from open-source footprint

Staff
76signal

Ronalfy is a full-stack developer with a notable mobile/Kotlin component, building entirely original work (forkRatio 0.04, zero abandoned). Projects include Osiris, an in-browser cloud development platform, and Finanzen, a Kotlin app. His most-starred repo reaches 18, and consistency is high, though polish scores low and nothing is deployed yet — suggesting strong building momentum that's still rough around the edges. A versatile early-to-mid developer spanning web and Android.
