I started developing for iOS back in 2010, and in 2011 I started learning Ruby and a bit of HTML / CSS. In this time, I shipped two apps and two games on my own, then continued as iOS Lead at DeinDeal, one of the largest flash-sales companies in Switzerland. I wanted to start blogging, but since I couldn't really find anything to fit my needs, I created my blog with Sinatra + ERB, DataMapper and Dropbox and hosted it on Heroku. The idea was to write Markdown files from anywhere and any platform, upload them to Dropbox and sync them with the database.
Notable iOS side projects include an iOS 7-style passcode and an MM / YY picker.
