Portfolio & about

Hi — I’m Daniel.

iOS developer. On the side I build my own apps, Shortcuts, and an arcade remake. Off the clock, the guy in the red cap by the sea: old-school hip-hop on an Akai MPC, Nintendo, and karate.

About me

Into the Apple world because Atari went bankrupt. Hip-hop, Nintendo, and an MPC come with that — not a résumé.

    solutio — dental software charly

    Four years at solutio on the dental software charly. I built up the iOS department there and developed iPad apps.

How it started

  • Berlin

    Hip-hop as a teenager

    Hip-hop in Berlin, on Cubase then. Direct-to-disk and MIDI.

  • Nintendo

    Consoles that ran in Germany

    As a kid, imported and modded consoles so they would run here. One of the first small businesses. Would rather play Nintendo when his head is full.

  • Atari

    Saved for two years for an Atari Falcon 030, then put it in a 19-inch rack. Hardware and system from the inside.

  • Today

    Akai MPC

    Old-school hip-hop in free time, now on an Akai MPC Key 37.

Three highlights

A game, a Shortcut, a Mac app. Short and honest — no marketing gloss.
