• Linux & Open-Source Migration: Led an organization-wide migration from Windows and Microsoft Office to Linux and OpenOffice.org, implementing LTSP (Linux Terminal Server Project) to centrally manage approximately 20 workstations supporting 90 users. The migration improved system stability, reduced endpoint vulnerabilities, and avoided substantial software licensing costs.

• Monitoring and Operations: Implemented and maintained infrastructure monitoring with Icinga/Nagios and SNMP, proactively identifying performance issues and supporting capacity planning and operational visibility.
• Backup and Recovery: Designed and automated a cross-platform backup workflow using Bash, rsync, Cygwin on remaining Windows systems, cron scheduling, and Bacula. Configured SSH public-key authentication, host-key validation, and restricted backup accounts, and tested restores to verify recoverability.
• Web & Business Systems: Developed and maintained a WordPress-based website and e-commerce platform integrating event promotion, product sales, and social media while supporting PCI-compliant payment processing.
