Dave Juntgen
I'm Dave Juntgen, a senior engineering leader at Amazon Web Services. I've built my career in Enterprise Support, where the job is keeping the world's largest cloud workloads healthy — and where you learn that reliability is a discipline, not a feature. Twenty-six years of software and Linux sit underneath that. At home I run a small datacenter and build AI-agent systems — and I write about all of it.
