About the Book

Strategic Domain-Driven Design is about communication and collaboration. But once you have strategized, communicated, and collaborated, where do you put the code you write? That’s where this book fits.

I’m taking a “code first” approach and here’s why. There’s been a strong tendency for developers to jump straight to the “tactical” patterns of Domain-Driven Design because they’re concrete and relatively straightforward to implement. The abstract concepts such as “Bounded Context” are much less obvious.

Strategic Domain-Driven Design tells us that our code should fit inside one or more Bounded Contexts. But what is a Bounded Context, and where should we draw the boundary?

The answer is, “it depends on the situation”, which is not terribly helpful when we need to actually start implementing a feature. The problem, literally, is in figuring out where to start.

Here is where to start.

About the Author

Edward W. Barnard

Edward W. Barnard brings unique implementation expertise from programming Cray supercomputers at the hardware level, debugging systems at classified facilities, and solving critical Y2K infrastructure problems. His 20+ years at Cray Research included hands-on work with assembly language, operating systems, and I/O subsystems. He has published over 100 technical articles, helping developers implement solutions to complex problems. His cross-domain experience, from NSA troubleshooting to Saudi Aramco installations, provides practical insights into applying advanced problem-solving techniques across diverse technical environments.

Edward has transferred his skill of bare-metal programming the Cray I/O Subsystem (with only 131,072 bytes of local memory) to novel ways of managing Large Language Model token context windows, unlocking capabilities not yet taught in AI literature. When a skill dormant for 35 years becomes suddenly relevant again, he calls this The Time Travel Pattern.
