My name is Mark Maunder. I've been blogging since around 2003 when I started on Movable Type and ended up on WordPress which is what I use to publish today. With my wife Kerry, I'm the co-founder of Wordfence which protects over 5 million WordPress sites from hackers and is run by a talented team of 36 people. I'm an instrument rated pilot and I fly a Cessna 206 along with a 1964 Cessna 172 in the Pacific Northwest and Colorado. I'm originally from Cape Town, South Africa but live in the US these days. I code in a bunch of languages and am quite excited about our emerging AI overlords and how they're going to be putting us to work for them.
