Knowledge must be usable beyond its source
A strategy can make perfect sense in the room where it was written and still be almost useless everywhere else. The people in that room remember the discussion, the rejected alternatives and the diffi
Domain-Driven AI — DDD, Architecture, and AI-Assisted Software Design
Thoughts on domain-driven design, AI-assisted software development, bounded contexts, event-driven systems, and keeping software grounded in real-world business context.

Alignment Needs Bounded Ownership
When organisations talk about alignment, the conversation often moves towards shared goals, shared terminology and common ways of working. That sounds reasonable. It can also lead to a harmful conclus
Software development has always been an alignment problem
The phrase alignment problem is now strongly associated with AI safety. In that discussion, the concern is whether an AI system behaves consistently with human values and intent. That is not the subje
AI-assisted development needs boundaries
Most writing about AI-assisted development seems to settle into three positions. There is the productivity account, where an agent is judged by how quickly it turns a ticket into code, the prompting a
Internal, External, and Contract Models Should Not Be the Same Thing
Discussions about model separation often end up being discussions about boilerplate. One object arrives at a service boundary, most of its fields are copied into another object, and a similar conversi
Contracts Are Where Context Becomes Visible
Most writing about bounded contexts pays close attention to what happens inside the boundary. The model should use the language of the domain. Business rules should have a clear home. Concepts that me
AI Should Not Become the Source of Truth
Most discussion about AI-generated documentation focuses on accuracy. Can the model find the right information? Does it hallucinate? Can its answer be verified? Those concerns matter, but I have becom
More Material Is Not Better Context
Most discussions about context for AI-assisted development focus on how to give the model more relevant material. Larger context windows help. Better retrieval helps. So does adding the file, ticket o
Why DDD Matters More in the Age of AI-Generated Code
Generated code is cheap. Domain clarity is scarce.
