The Design Final 3 consisted of two rounds, the semifinal and the final. In the semifinals PereViki fought against wahyu.ts, and iamtong was against abedavera. Their task was to design a Topcoder social tool to allow social network -like community activity within Topcoder, following your friends and their achievements, posting updates and chatting, for example. In the end PereViki and iamtong proceeded to battle it out head to head in the final round. Their task in the Final round was to design an app to protect against allergy attacks in a predictive way, taking into account user allergies and combining this info with, for example, pollen levels in the vicinity or possible allergens in nearby restaurants’ food menus.
