Ryan de Melo

I'm a CTO and hands-on builder. Over eighteen years I've taken platforms from zero to production scale: a B2B API business from $0 to $1.1B, ML systems serving 550M+ recommendations a day, and the payments and credit infrastructure behind $22B+ in commerce. These days I build GenAI infrastructure for regulated enterprises.

This is where I write down the parts that don't fit in a slide: architecture decisions, what actually changes at scale, and the unglamorous work of building teams. Start below, or read more about me .
