Over mij
I'm a Flutter mobile app developer focused on a niche most developers overlook: apps that work reliably for users with limited connectivity, lowend 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.
