Vertical slices, Solo, and empathy — product engineering with Aaron D. Francis

Kent talks with **Aaron D. Francis** about **product engineering**: why ticket-taking implementation is losing ground to agents, what a **vertical slice** from UI to database really means, and how Aaron’s desktop app **Solo** came from a painful problem—not a feature spec. They go deep on **scratch-your-own-itch** products, separating agents from dev stacks, **Jobs to Be Done**, why users bring you **solutions** instead of problems, and how empathy (and letting go of “technically correct”) changes what you ship.
