Background

About Rasheed Jamal

From a young age, I was captivated by how systems and data worked behind the scenes. That curiosity evolved into a fulfilling 8+ year journey as a Senior Database Administrator, where I’ve architected and maintained high-availability (HA) environments across PostgreSQL, Greenplum, MySQL, and Oracle platforms for global organizations. At Afiniti, I led the optimization and replication of multi-node PostgreSQL systems, achieving 99.9% uptime, a 95% drop in downtime, and cutting backup windows by 50%—all while ensuring compliance, scalability, and seamless performance for enterprise clients in the U.S. and U.K. I’ve engineered zero-downtime migrations, designed cross-database integrations using postgres_fdw, and implemented disaster recovery solutions that enable true business continuity. I'm passionate about database performance, automation, and security. My experience spans cloud-native services (AWS Aurora), Greenplum clusters, and failover strategies that align with mission-critical objectives. Whether it's logical replication, HA clustering, or advanced query optimization, I bring a proven ability to turn complex data challenges into operational success.
