System Design Module Overview

The System Design Module manages a secondary category of challenges on the platform: architectural and high-level system design problems. Unlike algorithmic coding problems, these are heavily theoretical and often text/diagram-based.

Architecture

This module follows a standard REST architecture with a Redis cache layer to optimize the high-traffic grid views.
