About Me

I'm Robert Poetzsch, an indie app developer from Hofheim am Taunus, Germany.

With over 20 years in IT, I build apps that reflect my philosophy: keep it simple, keep it useful, keep it honest. Every app in the robspace lineup is crafted with SwiftUI and focused on solving one real-world problem without unnecessary complexity.

When I'm not coding, you'll find me playing guitar and singing in the metal scene, hiking the Taunus hills, or tweaking my homelab setup. 🤘
