Automated Relay Debugging System (QR-Logic v2.0)

Project Overview

The QR-Based Relay Debugging Website is a dynamic competition platform designed for high-energy technical events. It automates the coordination of relay-style debugging rounds, using unique QR code checkpoints to manage team transitions and track real-time progress.

Event Logic & Relay Mechanism

• QR-Triggered Progress: Implements a secure QR-scanning system that acts as a physical-to-digital bridge, ensuring team members are physically present at stations before unlocking the next debugging challenge.
• Live Leaderboard & Scoring: Features a real-time synchronized dashboard that calculates scores based on time-to-solve and code accuracy, providing instant feedback to participants and organizers.
• Role-Based Access Control: Includes distinct portals for participants to view challenges and for admins to monitor event health, manage time limits, and validate manual overrides.
• Session Persistence: Engineered to handle high-concurrency and network fluctuations, ensuring that team progress is saved instantly and can be resumed across different devices.

Technical Implementation

Frontend: Responsive, high-contrast UI built with HTML5, CSS3, and JavaScript, optimized for fast mobile scanning and real-time DOM updates.
Backend: Powered by Python and Flask, utilizing customized routing logic to handle the relay-based state machine and QR validation.
Database Management: MongoDB stores event logs, team credentials, and dynamic challenge sets, allowing for rapid retrieval during peak event hours.
