I am a seasoned database professional with more than 15 years of specialized experience, primarily focused on MySQL and MariaDB, both replication as well as Galera Cluster and InnoDB Cluster. Those skills are complemented by proficiency in PostgreSQL, ClickHouse, Redis, and MongoDB. My expertise lies in database performance analysis and optimization, as well as the design and implementation of robust, high-availability architectures. I possess in-depth knowledge of load balancing technologies, including ProxySQL, MaxScale and HAProxy. On PostgreSQL side I've been working with pgBouncer and pgPool. I have successfully managed complex systems in both AWS and on-premises environments, ensuring exceptional reliability and efficiency.
