This administrative expertise is crucial for businesses that rely on real-time data access.

4. Performance Tuning and Optimization Skills

PostgreSQL is powerful, but without proper tuning, it can slow down under heavy workloads. A reliable freelancer must know how to analyze query execution plans, optimize indexes, and fine-tune database parameters. When you Hire PostgreSQL Developers Freelancer, check their ability to improve system performance through techniques like partitioning, caching, and connection pooling.
