E-commerce — Black Friday Recovery & Prevention
Transformed a platform that crashed on Black Friday into one handling 15x traffic with zero downtime.
Background
Mid-market e-commerce platform. $50M annual GMV. Previous Black Friday resulted in 4 hours of downtime and $2M in lost revenue.
The Challenge
- 1Application crashed at 3x normal traffic
- 2No load testing practice
- 3Kubernetes autoscaling misconfigured
- 4Incident response was chaos—no runbooks, no escalation paths
Our Approach
- Conducted architecture review identifying 12 critical scaling bottlenecks
- Implemented proper HPA with custom metrics
- Built load testing pipeline simulating 10x traffic
- Created incident response playbooks and conducted chaos engineering exercises
