Staff Backend Architect Rule: Scalability Starts with the Database

90% of web servers bottleneck not due to CPU execution speeds, but due to unindexed database queries and N+1 query cascades. Always:

Index Intelligently:Add B-Tree indexes to every foreign key and high-frequency WHERE clause column.
Cache Heavy Reads:Serve frequent, identical queries directly from an in-memory Redis cache rather than disk I/O.
Never Block Event Loops:Offload long-running tasks (email dispatches, PDF generation, media encoding) to asynchronous BullMQ workers.
