From Domain Discovery to Working APIs with AI

AI is making code generation cheap. The constraint in API work is shifting to design; how systems are defined, aligned, and governed over time. This talk outlines a practical approach to using AI as a design collaborator that augments and amplifies human capability rather than replacing it. Starting from domain discovery, you’ll see how AI extracts a shared vocabulary and carries it through OpenAPI definitions, documentation, security profiles, and test scripts all ending in a working prototype. Throughout the end-to-end example, the focus is on traceability: maintaining a clear, reviewable line from business intent to running system while sharpening the skills required to design well. For architects and decision-makers, this creates a consistent, reviewable process with measurable outputs. For developers, it reduces manual effort while strengthening core design skills. The result is a lightweight workflow that accelerates delivery while preserving control and capability.
