Cybersecurity & cloud infrastructure student in Enschede. Homelab nerd, helpdesk by day.

HBO ICT student at Saxion University of Applied Sciences in Enschede. Second year, graduating 2028. Focused on cybersecurity and cloud infrastructure. Currently 2nd-line Sysadmin at Livio in Enschede — production every day.

The philosophy: build real things, kept simple enough to defend in an interview.

What I work with

Linux & infrastructure — Linux, Proxmox, Ceph, Docker, Bash, systemd, journald

Cloud & IaC — Terraform, Ansible, Azure, AWS, GitHub Actions

Monitoring — Prometheus, Grafana, Alertmanager, blackbox_exporter, PagerDuty

Networking & security — OPNsense, WireGuard, Tailscale, VLAN, SSH hardening, auditd, UFW, fail2ban

Pentesting / forensics — Kali Linux, CTF practice, network security, IT forensics

IT support — 1st-line servicedesk, Windows Server, AD, Microsoft 365

What I run at home

A 3-node Proxmox cluster on consumer N100 mini-PCs. Every config file written by hand. Prometheus scrapes every 15s, Alertmanager routes to PagerDuty (SMS, then voice escalation), Tailscale provides the mesh. Storage on Ceph, networks segmented into management/storage/prod/trust VLANs.

Not click-and-done — that’s the point.
