Keeping systems up at 2 AM – Linux, VMware, Kubernetes (K3s), GPU-backed homelab, and an AWS pivot (SAA-C03 in progress). Keeping systems up at 2 AM – Linux, VMware, Kubernetes (K3s), GPU-backed homelab, and an AWS pivot (SAA-C03 in progress). 5+ years enterprise ops including finance uptime work, 2+ years running GPU-backed Kubernetes homelab, AWS SAA-C03 in progress.

Hi, I'm Chris. I run infrastructure – from finance-grade Windows/VMware estates to a GPU-backed Kubernetes homelab – and I'm shifting into night-shift infrastructure, NOC, and cloud operations roles. This site is my technical portfolio: it shows how I think about reliability, observability, and practical AWS/Kubernetes adoption.

  • • GPU-Backed Homelab: K3s cluster running vLLM inference on NVIDIA L4/A4000/T4 GPUs, 10/25GbE networking, ZFS storage, full Prometheus/Grafana observability stack.
  • • Enterprise Operations: 5+ years managing Windows/VMware environments for finance/trading firms – 99.9% uptime, VIP support, off-hours incident response.
  • • AWS Pivot: Actively pursuing AWS Certified Solutions Architect – Associate (SAA-C03) to complement homelab and on-prem experience.

Night-shift infrastructure focus. If you need someone who can keep systems stable when everyone else is asleep, let's connect. Seeking night-shift infrastructure & NOC roles. Available for CloudOps, infrastructure operations, and off-hours support positions (Philadelphia or remote). Ready for night-shift operations. If you're hiring for infrastructure, NOC, or CloudOps roles with off-hours coverage, I'd love to discuss how my homelab and enterprise background can help.

About Christopher Rothmeier

I'm an infrastructure operations engineer with a focus on night-shift work, GPU-backed Kubernetes infrastructure, and AWS fundamentals. My background spans finance-grade enterprise ops (Windows/VMware estates with 99.9% uptime requirements) and a serious production homelab where I run K3s, vLLM inference, and a full observability stack. I'm pivoting into CloudOps and NOC roles that value hands-on infrastructure work when systems matter most – at 2 AM.

Enterprise Operations Background

I've spent 5+ years managing enterprise infrastructure for finance and trading firms, where downtime isn't an option. This included VIP/executive support, after-hours incident response, VMware virtualization at scale, and maintaining strict security compliance. I've lived the reality of keeping critical systems stable under pressure – which is exactly the mindset I bring to night-shift infrastructure roles.

GPU-Backed Kubernetes Homelab

  • Hardware: K3s cluster running on bare metal with NVIDIA L4, A4000, and T4 GPUs for vLLM inference and AI workloads.
  • Networking: 10GbE/25GbE infrastructure with proper VLANs, routing, and security segmentation.
  • Storage: ZFS-based storage pools with snapshots, replication, and backup automation.
  • Observability: Full Prometheus/Grafana stack with custom dashboards, alerting, and log aggregation (Loki).
  • Why it matters: This isn't a toy setup – it's production-grade infrastructure I use to validate technologies, test disaster recovery procedures, and stay current with Kubernetes/cloud-native patterns before deploying them in enterprise environments.

AWS Pivot & What I'm Seeking

I'm actively pursuing AWS Certified Solutions Architect – Associate (SAA-C03) to complement my on-prem expertise with cloud fundamentals. I'm looking for night-shift infrastructure, NOC, or CloudOps roles (Philadelphia or remote) where I can leverage both my enterprise operations background and homelab experience. My ideal environment values reliability engineering, observability, and the kind of hands-on troubleshooting that keeps systems running when everyone else is asleep.

If you're hiring for infrastructure operations roles with off-hours coverage, I'd love to discuss how my experience can help your team.
