Chi sono
Hello and welcome to my profile!
I am a professional Flutter Developer specializing in high-quality mobile applications for Android (Java/Kotlin/Flutter). I don't just build apps; I focus on solving the common and complex problems that often stop apps from succeeding.
My expertise is structured around four core areas:
1. App Development & Maintenance
My primary goal is delivering clean, high-performance apps. I specialize in the maintenance side of development, including:
Diagnosing and fixing app crashes and null safety errors.
Updating apps to the latest target SDK to maintain apps.
