About

Product over hype. Judgment over speed.

I’m Ronaldo. Roarca is where I build my own products — solo, and without rushing. I’d rather make a few things well than many halfway: I care more about judgment than speed, and about whether what I build actually gets used, not whether it looks good in a demo. No hype, no shortcuts, made for the place I live. Pura vida.
