About
I'm a software engineer based in Mexico City with a passion for building polished, performant mobile experiences. Over the past 7+ years, I've shipped products across fintech, education, and consumer platforms — from greenfield apps to scaling existing products past a million users.
My core expertise is in React Native and TypeScript, but I'm comfortable across the full mobile stack including native modules in Kotlin and Swift, automated testing with Jest and Detox, and CI/CD pipelines. I care deeply about code quality, accessibility, and shipping things that actually work.
