About

Infrastructure that simply works.

Understood technically — and from the user's perspective.

I'm a passionate IT professional based in Switzerland with over 10 years of hands‑on experience designing, deploying, and managing complex IT infrastructures. My expertise is backed by 8 certifications: MCP, MCSA, MCTS, Microsoft ISA Server 2006, MCSE 2003, CCNA, CompTIA Network+, and QNAP QuTS Professional 2026.

Networking runs on the UniFi stack: WiFi and WLAN design, VLAN segmentation, DHCP & DNS, firewall and security policies, site‑to‑site and remote VPN. Virtualization runs on Proxmox VE, VMware ESXi & vCenter, Microsoft Hyper‑V and Parallels Desktop — live migration, snapshots, central monitoring. Storage and backup run on QNAP (QuTS hero) and Synology NAS with RAID, immutable snapshots and offsite replication.

What sets me apart is my holistic approach. Whether it's the Apple ecosystem end to end — Apple Home & Loxone automation, Apple Family Sharing and iCloud+ with Private Relay and custom mail domains — macOS fleet management with Munki & MDM, self‑hosted AI with Ollama, or enterprise backup with a 3‑2‑1 strategy — I bring experience from government, hospitality, and enterprise environments, applying modern technologies with precision and a solution‑first mindset.

Services

One ecosystem, centred on my own services.

Hardware, platform, deployment, backup — every layer exists to keep the self‑hosted services running.

Self‑hosted services

Every other layer exists for these: running on my own hardware, reachable from anywhere, recoverable to any point in time.

Solo project · founder & engineer

A self‑hosted Mac fleet platform — built solo.

ownMDM is my own product: designed, developed and operated single‑handedly on a decade of hands‑on Munki and MDM practice. Software distribution, compliance policy, remote support and inventory for Apple fleets — from one console you host yourself, with strict row‑level tenant isolation, SAML 2.0 SSO, an append‑only audit trail and no data ever leaving your infrastructure.
