Szabolcs Katona

Twelve years in IT infrastructure, from the help desk to running the whole estate. What I am good at is turning an inherited, undocumented environment into one that is visible, measured and backed up — without anyone noticing the move while it happens.

1. 01

   Infrastructure

   Virtualisation, backups and networks the next person can understand.

2. 02

   Security

   Layered defence that everyday work does not route around.

3. 03

   Automation

   What was done by hand twice becomes a script the third time.
