The original title is "How to Learn System Design: A Roadmap by Career Level"

Short summary

System design is a learnable skill built on making defensible trade-offs under constraints, not memorizing designs. Master fundamentals (networking, databases, concurrency), then building blocks (caching, sharding, load balancers) one by one, understanding when and why to use each. Practice with 8-12 canonical systems in timed sessions, calibrating depth to your career level—junior needs basics, senior needs trade-off justification, staff needs multi-region strategy.

• •System design is a skill of making defensible trade-offs under constraints, not trivia memorization
• •Follow a structured progression: fundamentals → building blocks (one per day) → full systems (one every two days) → timed practice (two per week)
• •Use a sustainable 40-minute daily rhythm; calibrate your target depth to avoid under-preparing or wasting months on irrelevant complexity
