SaaS platforms whose PostgreSQL database is hitting 95%+ CPU, running out of max connections, or slowing down as tables cross 100 million rows frequently search to hire a freelance PostgreSQL performance tuning, table partitioning & PgBouncer programmer. I am Aldian Fazrihady, a Senior Freelance Full Stack Developer and PostgreSQL Architect available via Upwork.
Core PostgreSQL Performance & High-Scale Architecture Capabilities
- `EXPLAIN (ANALYZE, BUFFERS)` Query & Index Optimization: Replacing sequential table scans with composite B-Tree covering indexes (`INCLUDE`), partial indexes (`WHERE deleted_at IS NULL`), GIN trigram/JSONB indexes, and GiST spatial/range indexes.
- Declarative Table Partitioning & Archival: Partitioning multi-hundred-million-row audit logs, events, and ledger tables by time (`RANGE`) or tenant (`HASH`) with zero-downtime `pg_partman` automation.
- PgBouncer Transaction Pooling & Autovacuum Tuning: Supporting 10,000+ concurrent serverless/container connections without exhausting PostgreSQL backend processes or triggering transaction ID wraparound.
Frequently Asked Questions
Can you optimize our slow PostgreSQL queries without taking our production database offline?
Yes. All index additions use `CREATE INDEX CONCURRENTLY` with `lock_timeout` safety guards so live read/write traffic is never blocked.
