IT Systems Administrator

I am an IT Systems Administrator with more than a decade of experience supporting government IT operations, infrastructure, and digital services. My work combines Linux administration, virtualization, network security, web hosting, cloud backup, and full-stack PHP development.

I manage virtualized environments using Citrix XenCenter, VMware, and Proxmox, including provisioning and maintaining multiple virtual machines. I am experienced with Linux server deployment, system hardening, user and permission management, package administration, process monitoring, backups, and Bash automation.

I build and maintain web applications with PHP, Laravel, and CodeIgniter. My development experience includes thematic dashboards, dynamic transaction and data-management systems, access-level management, API integrations, authentication, and single sign-on implementations.

I work with Docker and Kubernetes multi-node environments and am currently developing CI/CD pipelines with GitHub Actions. I also implement monitoring and backup solutions using NAS Synology, Google Cloud, Google Storage, and Amazon S3.

My infrastructure expertise includes firewall and network configuration, MikroTik, FortiGate, VPN, VPS, mail servers, domain and email security, Cloudflare, WHM/cPanel, CWP, aaPanel, and ISPConfig. I also provide IT consulting for government organizations, with knowledge of ISMS ISO 27001, ITSM, cybersecurity policy, and risk management.

I am currently pursuing a Master of Informatics focused on Business Transformation Intelligence. I hold professional certifications in IT business analysis, information security management systems, internal audit, business process engineering, and e-government risk management, and I have advanced English proficiency.
