I've been writing code and building information systems for well over a decade now, starting in 2003 with full-stack web development using Visual Basic .NET and then PHP through to web front-end development using (VueJS) Javascript and Typescript, and now completely focused on mobile application development using native iOS and Android tool sets.

I build apps with modern tools and techniques in iOS and Android app development, specifically using Flutter, SwiftUI and Jetpack Compose for user interface development and then (Swift) Combine and (Kotlin) Flow for programming reactive + asynchronous data streams. This, of course, is in addition to combining those tools with the existing legacy techniques and APIs for building real-world applications.
