For most of 2014 I contributed to the development of the Jumbo Supermarket App for iOS. An agency called IceMobile was developing it and they hired me to join the development team in Amsterdam.
I added many features to the app and even implemented custom annotation clustering on the map view using a data structure called Trie. I even helped refactor the app to use AutoLayout when it was introduced by apple.
Also participated in a "Food hackathon" where I helped make some Indian food!
