I got to work with Mar and z0mbi to create the website portion of the official DEFCON Badge Challenge! My contribution was creating the back end and hosting for a challenge that could scale to 30,000 simultaneous users and perform the mathematical calculations required to detect object collisions in the 2D tile pattern.

I built the app in AWS using core serverless offerings (S3, API Gateway, Lambda, & DynamoDB) using event-driven workflows.

The team had a grand total of about 6 weeks to build and test the app before getting handed to a large audience of hackers. Needless to say, we received a good bit of "free pentesting".
