I worked with three guys to build a product in Retsly/Zillow Hackathon (zip.code 2015: Retsly Real Estate & Public Data Hackathon)
We established a platform and iOS app to search events, foods, drinks, party, gym pets, schools near a certain address by integrating Zillow/Restly and Instagram APIs, using Natural Language Processing, Machine Learning and Deep Learning techniques, AFNetworking, Cocoapods.
Even though we used a lot of cutting edge and fancy technology but didn’t get the prize since the judge prefer those who consumed tons of Retsly API which is emphasized in the rule.
For these kind of Hackathon which is completely supported by a company, if you want to win and you have to match the requirement as much as possible rather than show the capability in mastering high end technology. Anyway, beautiful User Interface and connection with the host play a significant role in the competition, good luck for next game.
