What is Tabbycat?

Tabbycat helps organizers run debating tournaments: matching teams for rounds, assigning judges, collecting results, and publishing standings. It supports British Parliamentary and several two-team debate formats.

My contribution

I designed and developed the Tabbycat software website in 2022. The Tabbycat Debate Association included my implementation in its official website, and the page credits “Designed by Tanzil Ahmed.”

The links below show the published website, my source code, and the change that added it to the official website repository.
