James worked with Information Technology (IT) subject matter experts, hiring managers, CIOs, and CISOs worldwide. I've worked as a security consultant, presenter, certification program designer, and curriculum designer for over 20 years.
James has worked extensively with emerging and newly-adopted technologies, mapping their progressive adoption (or lack of adoption) throughout the IT industry. I've worked with individuals and organizations to implement open source (including Linux), blockchain, and Web technologies.
James is also an award-winning author, blogger, and presenter. I have written titles for O'Reilly Media, McGraw-Hill, Prentice-Hall, IBM, Wiley, and Elsevier, among many others. I am also a regular contributor to various journals, including Admin Magazine, Ubuntu User, and Linux Magazine.
