I'm working as a freelancer, mainly focused on PostgreSQL database administration and architecture. Integrating PostgreSQL with other services. My experience as a PostgreSQL Database Administrator is above 2,5 years with good Linux background (above 15 years of experience as a Linux engineer). During this time I've been installing PostgreSQL servers on cloud infrastructure and deploying in docker containers. Building high-available clusters and replication. Planning backup and restore strategies. Optimizing server configuration. Tuning PostgreSQL parameters for better performance. Migrating data to PostgreSQL from other databases and loading data from external sources (CSV, TXT, JSON). Building monitoring systems (Prometheus+Grafana) for health-checking PostgreSQL clusters.
