About Me
I’m Ronald Gaupin, an experienced IT professional with over 16 years of hands-on expertise in building, securing, and optimizing enterprise-level infrastructure. I specialize in Linux system administration, network design, cybersecurity, and virtualization — with a proven track record of maintaining resilient environments that support thousands of users.
My work has included architecting multi-site networks with hundreds of access points, managing enterprise collaboration platforms like Nextcloud and Google Workspace, and implementing robust disaster recovery and backup strategies. I’m also proficient in scripting with Bash and Python, and have led teams in both technical operations and security compliance.
