"I'm an iOS developer and designer, based in Berlin, with 3 paid apps in the App Store and an open source project just launched which enables speech recognition and text-to-speech on the iPhone and iPad."

Collaboration

Hire Me

"I am available for iPad/iPhone/iOS consulting and shorter contracts (4 months or less). I have experience with several of the more complex iOS APIs such as Core Audio, Quartz 2D, Core Data, and more. I am available for local work here in Germany or other nearby EU countries, but I am also experienced at working as a distance member of a team, and I wrote my app AllHours (http://www.politepix.com/allhours) partially to make the job of finding optimal meeting times for teams with distance workers easier."

Portfolio

3 Numbers

What I did: "I designed and developed this project from start to finish."

 

AllHours

What I did: "I designed and developed this project from start to finish, including its unusual UI and its extensive backend written in Core Data."

 

AllEars

What I did: "I designed and developed this project from start to finish, including development in Core Audio/RemoteIO, Core Data and OpenGL."

 

OpenEars

What I did: "OpenEars makes use of two other open-source libraries of long standing, CMU Pocketsphinx and CMU Flite, which I'm not directly involved with. I designed an iOS API for making use of them on the iPhone, with continuous voice recognition on a background thread, UI hooks, and monitoring of Audio Session states in order to be able to respond to changes in the audio environment, developed it using Core Audio, C, and NSThread among other technologies, created a perl installer for its static libraries, and extensively documented its installation and use."
