About Me

I'm an ICT apprentice based in Zürich, currently completing my ICT-Fachmann EFZ through ESPAS. My journey in IT started with a genuine curiosity about how computers, networks, and systems work — a curiosity that has grown into hands-on expertise.

I've worked across a wide range of real-world scenarios: setting up enterprise-style server infrastructure, building home lab environments, configuring virtualisation platforms, and even experimenting with local AI setups. I approach every problem analytically and methodically, and I thrive when learning something new.

Outside of IT, you'll find me reading Sci-Fi & Fantasy novels, training in boxing and fitness, or tinkering with computer hardware.

Debian Home Server

Configured a fully functional Debian home server with Apache web server, SSH remote access, static IP configuration, and local website hosting — managing all networking and service setup independently.

Proxmox VM Lab

Planned and deployed multiple Debian virtual machines in Proxmox as a dedicated server testing and learning environment — great for safe experimentation without risk to production systems.

Local AI Environment

Set up and debugged a fully local AI inference environment using Open WebUI, llama.cpp, Python virtual environments, and GGUF model formats — running large language models entirely offline on local hardware.
