Tony Mason, PhD, is a computer systems researcher, architect, and hands-on technical consultant with nearly four decades of experience solving difficult software and systems problems.

He works with organizations facing technically consequential questions where the right answer is not yet clear: evaluating an architecture, investigating performance or failure behavior, assessing a technical claim, exploring an unfamiliar design space, or determining whether a proposed system can actually work.

Engagements range from focused architecture and technical-diligence reviews to hands-on investigation, modeling, simulation, prototyping, and implementation. The objective is not simply to recommend a direction, but to develop enough evidence to understand why that direction is justified.

Dr. Mason's background includes operating systems, storage and file systems, distributed systems, cloud and I/O architecture, formal modeling, and AI/LLM systems. He spent 22 years designing Windows file-system and kernel software for more than 160 technology companies and previously worked on distributed systems at Stanford and Transarc. He holds a 2025 PhD in Computer Science from UBC, is the primary inventor on 12 issued U.S. patents, and co-authored lex & yacc and Windows NT Device Driver Development.

Current work includes AI reliability and governance, systems simulation, storage and I/O architecture, and research prototypes for emerging computing systems.

Windows NT Device Driver Development (OSR Classic Reprints)

W. Anthony Mason, et al

For years, this has been the definitive and comprehensive technical reference for software engineers, systems programmers, and any engineer who needs to understand Windows NT systems internals. While this text has a fresh new look on the outside, the text, pictures, code samples and references on the inside are vintage 1998. Nevertheless, the book retains a tremendous amount of value in its clear (erudite even) descriptions of the Windows NT operating system architecture and internals; information on the implementation of standard Windows NT kernel mode drivers; Key details on the workings of Windows NT I/O Manager; and detailed technical discussions on interrupt management and synchronization issues.
