About TeamsCode

Our mission and team

TeamsCode

From in-person events to virtual contests

TeamsCode is a student-run 501(c)(3) non-profit that works to encourage middle school and high school students to study computer science. We work with teachers and sponsors to create awesome programming contests – both online and in-person!

Chris Elliott and Alan Bi founded TeamsCode at the beginning of 2017. Both of them participated in local programming contests and noticed a lack of representation from their school. They set about to change that by organizing the first-ever Mercer Island High School Programming Contest on April 1st, 2017. Since then, TeamsCode has expanded its influence across three states in in-person events.

Under the impact of a global pandemic, TeamsCode launched its first virtual programming contest in summer 2020. With more than 290 participants showing up to the event, it became TeamsCode's largest contest in history until spring 2021. Since our first virtual contest, TeamsCode's influence has expanded from the United States to more than 20 countries. We organized several more virtual events with a vast improvement in problem quality, contest experience, and contest participation.

As of summer 2021, TeamsCode's contest has three divisions featuring curated problems in different difficulties. In the future, we hope to continue our mission of bringing an enjoyable and inspirational team programming contest to everyone interested in computer science.
