This site is a small excrept from my portfolio from work done over the past few years. Not all projects are listed since many projects have been completed under a non-disclosure agreement.
Working as a Freelancer from Berlin since 2009 I have worked on many different projects. Ranging from developing custom iOS applications for use in the Enterprise to Websites for small businesses. Outside development work I am also available for consultancy on business ideas, hardware purchasing and furthering the sales of your business.
