Über mich
In IT since 2010, freelancing since 2018, running client infrastructure through my own company Line Markt LLC since 2022.
I keep small production systems running for founders and small companies without an ops person.
Day to day: Linux and Windows servers, Proxmox, Docker and Coolify, firewalls and VPNs, monitoring that alerts before the customer calls, and backups I have personally restored to verify. I also fix SPF, DKIM, DMARC and MTA-STS so your mail reaches the inbox.
I measure before I change anything and verify after. If something is outside what I can deliver, I say so.

Arbeitserfahrung
Infrastructure and Security Engineer
Line Markt LLC • Selbstständig
Mar 2022 - Present • 4 yrs 6 mos
I run the infrastructure for four business customers on my own Proxmox cluster: two hosts, 15 virtual machines and 7 LXC containers, mixing Windows Server, Windows 11 and Debian. Active Directory with least privilege rights, network segmentation with a separate firewall ruleset per customer, MFA on every remote access. SIEM with Wazuh for log collection, file integrity monitoring and PowerShell auditing. Backups in three copies with a monthly automated restore test including boot verification: measured 12 GB restored in 2 minutes 19 seconds. Monitoring with Grafana, Loki and Prometheus, alerting over two independent channels. Over 100 of my own scripts for maintenance, monitoring and self healing. I measure first and verify after. A backup that has never been restored is not a backup, and an alert nobody receives is not monitoring.
