TALK
Domain-Driven Harness Engineering
DDD has been telling us for 20 years that a shared language inside a bounded context is the strongest predictor of a software projects long-term success. The same is true for LLMs and most teams adopting agentic development are paying the price for ignoring it.
The same methods you’d use to align a team with a domain expert, explicit ubiquitous language, bounded contexts and modeled handoffs, are exactly what move an LLM from improvisation to reliable collaborator. The AI coding harness becomes a modelling artifact.
Let me show you how to move beyond opinionated agentic workflows and build & evolve your own domain driven harness in collaboration with your team.
You’ll leave with concrete patterns on how to design, evaluate and evolve your own workflow, regardless if your collaborators are human, machine, or both.
