November 22, 2021 TCO21 Final Day Recap

Here we are – the ultimate conclusion to the ultimate week.

On the seventh and last day of TCO21, the only competition left was the Design Final 3, where the ultimate design champion was decided. After that, this crazy week was finally wrapped up by the Awards Ceremony we were all waiting for, where all of our champions for this year were announced for each Topcoder track.

Find the Youtube recording for this exciting final day here.

Design Final 3

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.
