WIREGUARD SETUP
I spent some time figuring out how WireGuard works and found the guidelines, including the official ones, to be rather complex. So, I’m jotting down my learnings here.
AUSTRALIAN TAX INVOICE GENERATOR
As I embarked on my first contractor gig, I was asked to provide my own tax invoice. Having dealt with countless invoices over the years, I assumed it would be a simple task.

OLD TWITTER DELETER
My new personal project automatically clean up old tweets.
ADD HTTP AUTH USERNAME INTO ENVOY PROXY LOGGING
Oddly couldn’t find any useful copy & paste solution for this.
