SQL administration in production environments—not just dev/test, not just managed RDS - Deep understanding of Postgre
SQL internals: WAL mechanics, MVCC, vacuum processing, the query planner and optimizer, connection handling, and lock management - Proven experience with physical and logical replication: setup, monitoring, failover, and troubleshooting split-brain scenarios
- Strong SQL performance tuning skills: reading EXPLAIN ANALYZE output, identifying indexing strategies, understanding join algorithms, and resolving locking contention
- Solid Linux systems administration (we run Ubuntu)—comfortable with systemd, file system performance, memory management, and networking fundamentals
