Mark has been a freelance technology writer since 2004 when he wrote a regular eBay column for AuctionBytes (now renamed eCommerceBytes). He also contributed articles to the now-defunct Bookologist, Google Tutor, and a few other sites now lost to time (although you could probably find them on the Wayback Machine). Then came a couple of years of soul-destroying English teaching work before MakeUseOf asked him in 2007 to become the managing editor.
Until 2016, Mark remained at MakeUseOf as a senior contributor, but he now branched out into other clients and other areas of writing expertise. He has become an expert at cyber-technology and online privacy, online marketing, and online business. He was the Content Management Director for Quiet Light Brokerage, and a contributing writer to outlets such as Lifehacker, NowSourcing (where a story of his ended up on the front page of Yahoo.com), GroovyPost, Lifewire, Trendblog, Small Business Trends, and PC World.
In 2017, Mark decided to realise a dream of his and started self-publishing his own spy fiction novels. With thirteen books now published, he has received rave reviews for his Department 89 series and Scorpion series. Customers have compared him in reviews to Clive Cussler, Dan Brown, and Mark Dawson.
