About
Golfredo Pérez Fernández
Software engineer from Venezuela. I ship under GoldevLab with two main lanes: Rust + Resuma for microsaas, and TypeScript + Qwik for larger product PWAs — plus Web3 when the job is on-chain.
ACUPATAS, MOA Education, Moa Academy, and Koolinart run on Qwik/TypeScript. YouTubeForge, UnderKb, PDFForge, and the sister tools run on Resuma/Rust. Same craft, different runtime.
Goldev is the front door: selected work, stack, and how to reach me.
