Richard Ziolkowski

I am a Canberra-based software developer. I make iPhone apps, web tools, games, courses, local AI systems, and small developer utilities. Most of the projects here started as something I wanted to use, teach, or play myself.

I usually work in Swift and SwiftUI, React and TypeScript, Python, and Docker. I care about the full slice: the product idea, the app, the content, the screenshots, the deployment, and the proof that it works outside a demo.
