Systems Administration and IT Management
I have extensive experience managing server infrastructure, deploying and maintaining various self-hosted servers, and administering VPN solutions for user groups. My role includes managing both on-premises (Synology, QNAP NAS) and cloud-based (DigitalOcean, Linode, Contabo) systems, optimizing network configurations, troubleshooting issues, and ensuring robust security practices. Additionally, I support end-users, handle hardware maintenance, oversee IT assets, and manage procurement processes for IT and office equipment.
Network and Security Administration
I am proficient in network setup and monitoring, VPN server deployment, and SSL management. I maintain secure communication for my organization through VPN access and routinely monitor SSL expirations.
Containerization and DevOps
I work extensively with Docker and Docker Compose for application deployment, including Nextcloud, OpenEMR, MariaDB, and Apache Solr applications, with projects spanning file storage solutions, medical records, and PHP-based applications. I also manage Docker-based CI/CD workflows, integrating with GitHub and Docker Hub to automate containerized deployments.
Cloud and Virtualization
I have experience migrating applications across cloud providers, using virtualization for testing, and implementing cloud-based backup solutions (e.g., rclone with Google Drive for incremental backups). This includes working with VPS providers and using Google Cloud Shell, Google Drive, and DreamHost to manage cloud-hosted resources.
Linux System Administration
I am proficient with Linux systems and shell scripting, regularly performing backup, restore, and system configuration tasks, and have managed services on both Red Hat and Ubuntu distributions. I favor efficiency in command-line workflows, preferring tools like top for monitoring and docker cp for file operations in Docker containers.
Web Development and Automation
I have experience with web technologies through my work on a todo application, which I structured as a multi-container Docker project with separate frontend and API components. I manage web configurations for applications hosted on WordPress and WooCommerce.
