In his teachings, he emphasizes the "High-Level Design" (HLD) before the "Low-Level Design" (LLD). He advocates for a top-down approach where complex mechanisms are initially treated as "black boxes." A database is a black box; a message queue is a black box. Only after the data flow is established and the API contracts are defined does he "open the box" to discuss the internals—sharding strategies, consensus algorithms (like Raft or Paxos), and caching policies.
