ÖBB Vienna, Austria
Architecture for train-to-land connectivity.
Senior Network Solution Architect
At ÖBB, I work on the network architecture connecting trains and land-based systems. That connectivity supports onboard services and departure readiness.
The architecture question +
Context. A connectivity loss before departure can prevent a train from starting its trip; a loss during the journey may leave the train running while some services become unavailable.
Design focus. Make those different service dependencies explicit in the topology, integration patterns, and recovery approach.

Network and security consulting.
Network & Security Consultant
At Base-IT, I worked as a Network & Security Consultant across enterprise networking and security. That hands-on consulting perspective informs my architecture work today.
Areas of responsibility +
Enterprise routing and switching, access control, segmentation, and network security. Connecting requirements with technical solutions that teams can implement and operate.
02 / Expertise
Three disciplines. One connected system.
A network is only as useful as its security, visibility, and ability to keep serving people.
01
Network architecture
From complex requirements to a coherent network. Topology, integration, and standards with a clear reason behind every decision.
Routing · Switching · WAN
02
Security by design
Trust boundaries that make sense in practice. Segmentation, access control, and policy that remain understandable as systems evolve.
Segmentation · Identity · Access
03
Operational resilience
Consider what happens when things change or fail. Recovery, observability, and degraded modes belong in the design conversation.
Visibility · Recovery · Automation
