Chapter VIIAboutThe person behind the pages.
Jonnathan MacKinnon, founder of MacKinnonTechJonnathan MacKinnon / Iwakuni, Japan

A bit about me.

Hi, I’m Jon.

I write software.
I also spend a lot of time with servers.

I build apps, manage a home lab, and study cybersecurity. I like working on both the screen you use and the server running behind it.

MacKinnonTech is where I share that work. Some projects start with a problem I need to solve. Others start with an idea I want to try.

Built in Iwakuni, Japan.
