I currently work as a Senior Software Engineer. Most of my duties involve developing and maintaining servers written in Ruby.

Tools I use regulary:

I have a Github profile. My most popular project is a macOS app to prevent accidental Command-Q.

I used to sell a macOS invoicing app called "Injoice". After more than 6 years, I wound the business down.

I graduated from one of Australia's top universities with a Bachelor of Engineering, majoring in Software Engineering.
