About Azius

Brian Catlin

Brian Catlin is co-owner and Vice President of Azius LLC. He started building and programming 8-bit microprocessors in 1977, switched to VAX/VMS in 1982 where he specialized in device drivers, and finally to Windows NT in 1992, specializing in device drivers and internals. Brian got into device drivers because he likes to write software that interacts with the real world; writing business software is his definition of torture. Brian also spent a great deal of time in the aerospace/defense world designing command centers, where he learned the discipline of specification writing and project management. Brian is a past Microsoft MVP for the Windows Driver Kit (they are no longer doing MVPs for the WDK) and is a moderator on Microsoft’s WDK forum. He¬†offers consulting services through his company, Sannas Consulting.

Jamie Hanrahan

Jamie Hanrahan is co-owner and President of Azius, LLC. He wrote his first device driver in 1976, for a hardware interface of his own design on an HP 2100 minicomputer. (He still sometimes finds hardware tools such as logic analyzers useful in driver debugging.) Later he worked for Digital Equipment Corporation, and received an “Instructor of the Year” award while teaching VMS internals and device driver classes. He also co-authored a book on Advanced VMS Device Driver Techniques. He has been working with Windows internals and drivers since the NT 3.1 Beta and has provided over 30 drivers to consulting clients. His consulting services are available through his company, Kernel Mode Systems. You may have seen some of his contributions to tech-oriented social media such as SuperUser.com.
