Demo profile

Mobile-first Web Engineer

Mar del Plata, Argentina·5+ years·Spanish / English

Bio

I build web apps that work perfectly on phones because that's where most users are. 5 years focused on responsive design, touch interactions, and mobile performance optimization. Started in native Android, switched to React Native, now I do progressive web apps. I test on real devices, care about bundle size, and know that 3G connections still exist. Beach town life means I'm flexible with hours but very disciplined with deliverables.
