Hi, I’m Yongho (JPIdad) — an infrastructure engineer based in Georgia.
By day, I manage IT infrastructure for enterprise clients — VMware vCenter environments, Windows and Linux virtual machines, Veritas NetBackup, Zabbix monitoring, and CyberArk privileged access management. I started my career on the software side before moving into infrastructure, so I’ve worked on the applications people use every day and I’ve also been responsible for the systems that keep them running. You can find my professional background on LinkedIn.
I started this blog for a simple reason: a lot of IT content online is either outdated, overly theoretical, or written by someone who has never had to support the system in a production environment. Everything here comes from things I’ve actually broken, actually fixed, and actually learned the hard way — backup jobs that “succeeded” but couldn’t restore, authentication failures at 2am, DNS issues that looked like something else entirely.
What you’ll find here
This blog is where IT infrastructure meets real life in America. You’ll find technical deep dives, lessons learned from real production environments, career experiences across three countries, and stories from everyday life as an infrastructure engineer and dad in the United States.
• Backup, Recovery, and Disaster Recovery
• VMware and Virtualization
• Monitoring and Troubleshooting (Zabbix, DNS, Windows and Linux servers)
• Career Lessons from Working Across Korea, Germany, and the United States
• Life in America as an Infrastructure Engineer and DadMy goal is simple: to share practical lessons, real-world experiences, and useful knowledge that can help fellow IT professionals solve problems and keep growing in their careers.
I was born and raised in South Korea, spent more than a decade working in Germany, and eventually made my way to the United States — three countries, three very different work cultures, and a lot of lessons along the way. I’m also a dad of three — the “JPI” in the blog name comes from my kids’ initials. When I’m not troubleshooting a server, I’m probably chasing them around the house.
Whether you’re an experienced administrator or just getting started in IT, I hope you’ll find something useful here. If something here saves you a 2am panic, it did its job.
