2. Key Senior Design Takeaways
Blocking Order-Flipping Arbitrage
- Under the Zomato Baseline, scammers successfully exploited the system 50 times, canceling their orders and immediately buying them back on secondary co-located accounts for a massive discount.
- CORO's Anti-Arbitrage Shield blocked 100% of these attempts by cross-checking location proximity, shared IP subnets, and recent cancellations.
Weather-Adaptive Thermal Decay
- Standard static thermal models degrade during seasonal extremes (like 38°C summers accelerating ice cream melting).
- CORO dynamically adjusts decay parameters based on ambient temperature. It successfully blocked 357 unrescuable orders, protecting customer experience and eliminating post-delivery disputes.
Interview Talking Point: "To protect restaurant brand value and platform margins, I designed CORO with a weather-parameterized decay model and a multi-factor anti-arbitrage check. By blocking nearby users sharing IP addresses or recent cancellation histories, we prevent order-flipping scams, while ambient temperature integration ensures we never deliver cold or melted items."
