I enjoy planning, building, and maintaining networks and the systems that run on them, ensuring that all processes relying on these networks can run smoothly.

My knowledge extends across all layers of the network:

✅ Finding the right cabling solution - whether copper or fiber optics

✅ Choosing suitable switches, routers, firewalls

✅ Planning IP networks and routing between them (IPv4 and IPv6; OSPF, IS-IS, BGP)

✅ Thinking through failure scenarios and implementing redundancies for fault tolerance.

The setup of the network doesn't have to be the end; I can also assist with:

✅ Installation and maintenance of Linux systems

✅ Management with Ansible

✅ Operation of various servers such as HTTP(S), DNS, DHCP

✅ Monitoring systems; data retrieval via SNMP

✅ Database systems (PostgreSQL, MySQL, SQLite)

✅ Software development with Python

✅ Version control with Git

✅ Telephony from home connections to corporate setups using VoIP (consulting on and operating cloud solutions, phone selection, or standalone VoIP servers).

I am also happy to provide theoretically oriented introductions to these topics.
