WordPress Origin Story

I started with WordPress when I first started working as a frontend developer.
I though I knew WordPress back then.

Things evolved naturally and thanks to Trew Knowledge I had a chance to improve my PHP and WordPress skills and be where I am today.

Next step is to start teaching and participating in talks.
