About Me

I'm Juan — a mobile developer who ships. I build Flutter apps from idea to production, publish them on both the App Store and Play Store, and maintain open source packages as a verified publisher on pub.dev.

I work across the full stack of mobile: UI, architecture, AI integrations, security, and deployment. When I solve a problem worth sharing, I open source it. 100+ public repositories, educational resources, and a growing community of developers who use my tools.
