Administering SaaS Linux systems. Mainly I design my small infrastructure, and fix or install things like:

  • LAMP - Apache, MySQL, nginx (including reverse proxy and load balancing)
  • L2/L3 networking and routing
  • ferm or iptables

But I am also infosecurity oriented,

  • ELK stack (elasticsearch)
  • Elastalert
  • Cisco Firepower

automation driven and really like things tidy, when it comes to code and config,

  • Ansible
  • git
  • VS Code
  • Python

tickets or even cables. And monitoring.

  • Datacentre experience
  • DCIM documentation tool
  • Grafana
  • Graphite, InfluxDB, Telegraf

Still learning

BIND 9 dns, cryptography.


Windows support and sysadmin, but moved my skillset to Linux before all the Windows 10 thing.
