You will get I will analyze and optimize your PostgreSQL database performance
Project details
I help businesses diagnose and fix slow PostgreSQL databases, optimize query performance, and improve reliability for production systems. With over 14 years of experience managing mission-critical database environments and supporting more than 20 enterprise clients, I specialize in PostgreSQL performance tuning, database troubleshooting, and cloud database optimization.
My expertise includes PostgreSQL, Amazon RDS, and Amazon Aurora, where I analyze slow queries, optimize indexes, tune configuration parameters, and resolve issues such as high CPU usage, locking, replication lag, and inefficient queries. I also help identify table and index bloat, improve vacuum/autovacuum behavior, and optimize database workloads for better stability and scalability.
In addition to performance optimization, I assist with high availability design, replication setup, and database migrations from systems such as DB2 or Oracle to PostgreSQL/Aurora. My goal is to deliver reliable, scalable, and well-tuned database environments that support critical applications.

My core strength is taking ownership of databases end-to-end: design → build → migrate → tune → monitor → automate → troubleshoot, and ensuring systems remain stable under real-world load.
What I do best (How I can help you)
✅ PostgreSQL Performance Tuning & Query Optimization
Diagnose slow queries using EXPLAIN / EXPLAIN ANALYZE, execution plans, and system metrics
Index strategy: btree/hash/gin/gist/brin, partial indexes, covering indexes, and workload-specific tradeoffs
Fix bottlenecks caused by locks, deadlocks, long transactions, connection storms, or inefficient queries
Identify and reduce I/O pressure, improve cache hit ratios, optimize autovacuum behavior
✅ Vacuum / Bloat / Storage Optimization
Troubleshoot and optimize VACUUM, autovacuum, analyze, and table statistics
Bloat identification + remediation (table/index bloat, long-running transactions blocking vacuum)
Maintenance planning with minimal disruption for large tables and write-heavy systems
✅ High Availability, Replication & Disaster Recovery
Design and support Streaming Replication, read replicas, and DR strategies
Failover planning, replication lag tuning, WAL behavior understanding, and reliability best practices
Production-grade HA thinking: RPO/RTO design, runbooks, incident playbooks, safe recovery steps
✅ AWS RDS / Aurora PostgreSQL (Cloud Database Engineering)
Architecture and operations for Amazon RDS PostgreSQL and Amazon Aurora PostgreSQL
Parameter tuning, scaling guidance, monitoring/alerts, backups and point-in-time recovery
Cost/performance balancing and safe production changes
✅ Database Migrations (Enterprise to Cloud / Cross-Platform)
Lead migrations such as Oracle → PostgreSQL/Aurora and DB2 → PostgreSQL/Aurora
Schema conversion approach, data movement strategy, cutover planning, rollback readiness
Zero/low-downtime mindset where possible (replication/CDC strategy when applicable)
✅ Production Support, Observability & Incident Response
Deep experience in production troubleshooting: CPU spikes, memory pressure, I/O saturation, replication lag, connection pooling issues
Monitoring and alerting using tools like DataDog (and database-native metrics)
Clear, structured communication during incidents: what happened, impact, mitigation, prevention
✅ Automation & Infrastructure-as-Code
Provisioning and standardization using Terraform
Repeatable deployments, environment consistency, and safer change management
Practical automation to reduce manual DBA work and improve reliability
Multi-Database Background (Adds real-world advantage)
Along with PostgreSQL/Aurora, I bring deep enterprise DBA expertise in DB2 LUW:
Backup & Recovery, upgrades, fix packs, and migrations
HADR implementation and support (including complex enterprise setups)
Cross-platform migrations Linux ↔ AIX, performance tuning, explain plan analysis
This background is valuable when you’re modernizing legacy systems or migrating from traditional enterprise databases into PostgreSQL.
Typical Projects Clients Hire Me For
PostgreSQL database is slow → root cause + query/index tuning + actionable fixes
AWS Aurora/RDS PostgreSQL health check → stability + performance + cost recommendations
Autovacuum/vacuum problems → bloat reduction + long transaction fixes
High availability setup or review → replication/DR plan + failover readiness
Oracle/DB2 to PostgreSQL migration planning/execution → safe cutover and validation
Production incidents → rapid troubleshooting + long-term prevention plan
What you’ll get working with me
Strong ownership and reliability mindset
Practical solutions (not just theory)
Clear communication, documentation, and step-by-step recommendations
Focus on stability, performance, and predictable operations for business-critical systems
If you share your current architecture, workload pattern (read/write), and pain points, I can propose a focused plan with quick wins and longer-term improvements.
