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.
