I’m Harpreet — a network and security engineer with a curiosity for how things work under the hood.

This blog is a personal space where I document what I’m learning: firewalls, load balancers, Linux, Azure, Git, and whatever else catches my attention.

Areas I work with:

  • F5 BIG-IP & load balancing
  • Check Point, Bluecoat & firewall technologies
  • Linux administration (CentOS, Debian)
  • Azure networking & cloud infrastructure
  • Scripting & automation

I find writing helps me understand things better — and if it helps someone else along the way, even better.
