Sobre mí
I'm a Flutter mobile app developer focused on a niche most developers overlook: apps that work reliably for users with limited connectivity, low-end devices, or little prior experience with technology.
My flagship project is an offline-first learning app built for rural users with no consistent internet access— it includes local database architecture with data migrations, native voice integration (text-to-speech and speech recognition with automatic fallback), and multiple interactive learning modules, all running smoothly on low-end Android hardware.

Designed and built a full-scale offline-first mobile learning application in Flutter, including local database architecture with versioned migrations, native voice integration (text-to-speech and speech recognition with automatic fallback), multiple interactive learning modules with different mechanics (calculators, branching scenarios, adaptive quizzes), and a production-ready signed Android build pipeline.
