Overview

GDSC RAIT's live leaderboard for Hacktoberfest 2024, used by 200+ developers throughout the event. Rather than polling GitHub, it consumes a webhook stream: each of the 1,000+ pull-request events is rate-limited, stored in MongoDB and re-ranks the board as it arrives.

The backend ran on AWS EC2 behind an Nginx reverse proxy and held 99.99% uptime under concurrent load for the whole event.
