Hi, I’m Fränk, your instructor.


Let me tell you my story that lead me to creating my first online course.

In 2011, I was at a point at which I didn't enjoy my job as a project manager anymore. I wanted to do something else, something that I enjoyed doing.

So I bought a book on PHP, and learned web programming. I quickly landed on WordPress as my tool of choice for creating websites.

But I didn't just want to be a WordPress engineer. I wanted to work on the best projects that the industry had to offer.

So I joined Automattic in 2013 as a Theme Wrangler working on WordPress.com. In 2015, I moved onto the WordPress VIP team.

This lead me to join Human Made, where I currently am a Principal Engineer. I've had the opportunity to lead large scale projects for clients such as NewsUKTechCrunch, and Red Bull Media House.

All this would not have been possible without all the articles, books, and courses that I worked through.

As a self-taught engineer I want to help other engineers improve their skills, their career, and ultimately their income.


WordPress unit testing has been a key skill for furthering my career.

And it will be a real career booster for you too.
