System Design

Weeks 1-2: System Design fundamentals and practice.

Weeks 1-2: Focus on System Design. Study distributed systems, scalability patterns, database choices (SQL vs. NoSQL), caching strategies, message queues, and API design. Review common system design interview questions and practice designing systems like a URL shortener, a social media feed, or a distributed cache. Understand trade-offs involved in each design choice.

Questions
