Monolithic relational database locking under heavy concurrent writes
Page load times degrading from 1.2s to over 6s during high traffic spikes

Development

Decoupled monolithic codebase into micro-frontends with Next.js edge caching and implemented Redis queue processing.

Architecture

Multi-region AWS Kubernetes deployment with Aurora PostgreSQL read-replicas and Cloudflare Enterprise CDN.

Results

Zero system outages recorded during Black Friday weekend with global sub-200ms page load speeds.
