In my current role, I am responsible for managing and optimizing the infrastructure supporting our platform and databases. I have set up a robust backup strategy for our production PostgreSQL databases using Barman, enhancing the reliability and recovery capabilities for critical data. I have also designed and implemented a comprehensive CI/CD pipeline for 16 microservices that integrate with PostgreSQL, RabbitMQ, Elasticsearch, and Redis clusters. This pipeline automates deployment using Python, Ansible, and Jenkins, resulting in improved efficiency and scalability.I oversee the full production installation lifecycle, utilizing Terraform for VM creation and Ansible or Helm for deploying services across environments, ensuring reliable infrastructure deployment. I also contributed to building a monitoring and alerting infrastructure with Nagios, Prometheus, and Grafana, integrated with tools like Jira and Slack, to maintain high system uptime.Additionally, I have successfully handled the complex upgrade of large PostgreSQL databases, ensuring minimal downtime and seamless transitions during version upgrades. My work focuses on maintaining system reliability, scalability, and efficiency through automation and proactive monitoring.
