I'm Santiago — an engineer at the point where mobile development meets AI. I build React Native and Kotlin apps, and I build the process machinery that lets AI write production code without anyone having to take its word for it.
Owner and operator
36 KB of static output, Lighthouse 1.00 across the board on every route, and a CV that prints from the About page under a mechanical one-page contract.
Six routes under a browser visual contract at three viewports, a print pipeline that refuses a second page, and a supply chain with install scripts off and every dependency pinned.
Startups and small teams that need an app shipped, not a deck about one
React Native + TypeScript or native Kotlin, from first screen to store release — including the unglamorous parts.
Teams that want AI speed without AI slop
Building with LLM toolchains, plus the discipline layer that makes the output trustworthy.
Hiring for a role, or need an app built? Email me — and if a private repo would tell you more than this site does, ask and I'll open it for you.
