Making IT easier for the people using it.

Systems engineer at an MSP. I build tools, automate workflows, run tenant migrations, and deploy systems that save my team and our clients real time — with an end-user experience that just works.

About

A bit about me

Hi, I'm Klaus.

I'm a Systems Engineer at CBIZ Technology, an MSP where I'm the person people come to when they've hit a wall. Whether it's a complex migration, a workflow that needs automating, or a problem nobody's had time to solve — I dig in and get it done.

I care about two things: saving people time and making things feel effortless. Whether it's my team or our clients' end users, every deployment, migration, and automation I build is designed around the experience of the person on the other end. That mindset has led to internal tools, workflow automations, and self-service platforms that save real hours every week.

I also mentor and train newer technicians, handle client onboardings and offboardings from the technical side, and make sure the team has the processes and tooling to work efficiently.

Homelab

Dell PowerEdge running Proxmox with LXC containers and Linux VMs, behind a Protectli Vault with OPNSense and proper network segmentation. Connected to Azure via site-to-site VPN, backed up to a QNAP NAS. Where I test before I deploy and break things without consequences.
