🧠Most systems are designed for “users.”
But who is the user, really?
In this post, I explore Persona-Driven Development (PDD) — a new spin on the familiar idea of personas, now enhanced with LLMs and agentic interfaces.
Forget static slides of “Marketing Mandy” and “Power User Paul.” With AI, personas can shape:
- 🎨 UI/UX flows (onboarding, layout, tone)
- 🧠Agent behavior (how an LLM responds, questions, or pushes back)
- đź› Engineering logic (feature toggles, safety rails)
- 🏛 Policy and rollout decisions (who gets what, and when)
🔍 Highlights from the post:
- A breakdown of the PDD Stack
- Real-world examples (learning apps, DevOps tooling)
- A call to design systems that adapt to people — not just personas on paper

đź’¬ Have you ever built features tailored to behavioral personas?
How would you scope or prompt your next AI agent differently using this idea?
