Database optimization is a critical skill for every backend developer. Indexes: Proper indexes can speed up queries by 100x. Use composite indexes. Query Optimization: Analyze queries with EXPLAIN ANALYZE. Avoid the N+1 problem. Caching: Cache frequently used data with Redis or Memcached. Connection Pooling: Manage connections with PgBouncer or ProxySQL. Partitioning: Split large tables into partitions. Range or hash partitioning. Read Replicas: Route read traffic to replica servers. Denormalization: Duplicate data when necessary for speed. Monitoring: pg_stat_statements, slow query log — detect performance issues early.

EXPLAIN ANALYZE is my best friend now. Found a missing index that was causing a 5 second query — now it runs in 12ms!
