I’m a PostgreSQL-focused database consultant with hands-on experience working on production systems, mainly around performance tuning, troubleshooting, and high availability. I’ve worked with read/write heavy workloads, where I’ve helped improve query performance, reduce load, and stabilize systems by optimizing queries, indexes, and configurations. I also have experience handling real production issues such as locking, slow queries, and I/O bottlenecks. On the infrastructure side, I’ve set up and managed replication and HA environments (Patroni/EFM), along with backup and recovery strategies including PITR and restore validation. I’ve also worked on database migrations (Oracle to PostgreSQL) using tools like Ora2Pg, FDW, and GoldenGate. Alongside PostgreSQL, I have experience with MSSQL, Oracle, and MySQL, mainly around performance tuning, backup/recovery, and administration. I focus on practical solutions—whether it’s fixing a slow query, stabilizing a production system, or helping improve overall database performance.
