System Design

Interview-ready system design preparation at senior/staff depth. Teaches a repeatable framework for clarifying requirements, estimating scale, choosing storage and messaging patterns, and narrating tradeoffs under time pressure — with classic design walkthroughs, failure-mode thinking, and timed mock drills. Light pseudocode where it clarifies mechanics (rate limiters, queue consumers); not a full coding track.
