From Requirements to a Defensible Design

Follow one small product from an ambiguous request through requirements, estimates, contracts, data, and a complete first architecture.

  1. 01 System Design Is a ConversationTurn an ambiguous product idea into explicit behavior, priorities, scope, and constraints before drawing infrastructure. 55 min
  2. 02 Estimate Before You ArchitectConvert workload assumptions into rough traffic, storage, bandwidth, and key-space requirements. 65 min
  3. 03 Turn Requirements Into APIs and DataDefine the system boundary, derive stored information from access patterns, and make failure behavior explicit. 65 min
  4. 04 Draw the Smallest Complete SystemConnect clients, application logic, and durable storage first, then add components only for measured pressure or failure requirements. 80 min
