About Benjamin

I am a creative developer with a strong interest in user experience.
Feel free to contact me for short expertise missions, advice and assistance, or for the realization of MVPs/POCs.

My preferred language is Objective-C, and I am very familiar with Cocoa and its Core Frameworks (i.e. Core Data / Graphics / Animation / MIDI), C, C++, and web technologies. I am an experienced user of the Adobe suite and capable of performing various types of light graphic work such as creating icons and assets for your applications.

I am passionate about Apple platforms and wish to work with associated technologies on high-value projects. My preferred fields are education, science, health, and music.
