Announcing the Winning Entries for CodeChef API Hackathon Powered by Alibaba Cloud!

3 min read

At CodeChef, we take pride in our innovative community that is constantly striving to create a better environment for all of us. In recent times, we received a lot of requests to open up our API so that our users could develop apps that would benefit the entire community and add new functionalities to the CodeChef platform.

Finally, on the 27th of August 2018, we launched our API and held our very first Hackathon – the CodeChef API Hackathon powered by Alibaba Cloud. This hackathon was held in the spirit of innovation; we already knew that our community was enthusiastic about using CodeChef data to create new resources for each other.

It brings us great joy to share with you the wonderful and innovative entries we received for the contest. It was not an easy task choosing between them, especially since we had to add an extra set of resources due to the sheer number of responses that we received, but we’re finally here with the list! Below is a glimpse of some of them. Check out the entries below and let us know what you think!

All the winners will win collective cash prizes worth $2400, internship interview opportunities at CodeChef, t-shirts and more as mentioned on the contest page.

On to the winners!
