My first experience with android started in 2013 with multi platform Alloy framework and Titanium SDK. After the first stable release of android studio in December 2014, I started using Java (which I studied at the faculty as a student). Over the years, I have developed more than a dozen applications. Some of them are paid, some are not, but the experience is there. In 2015 I started learning Swift language from Apple. That where my experience starts with Swift & SwiftUI. Currently I mostly develop iOS apps with mentioned stack and MVVM architecture. For persistence, I mostly use serverless architecture with Firebase/Firestore.
