As we venture into building on-device models, we're on the cusp of a surge in GenAI-related APIs and SaaS products. This shift resembles the past decade's trend towards backend and cloud services, and it behooves us to learn from that experience. I'm revisiting my earlier discussion on how to tailor SaaS APIs for mobile developers, using mobile developer personas for illustration.
A UX (User Experience) persona is essentially a fictional character embodying a particular user group that might interact with a product, service, or website in a consistent manner. These personas are not just random creations; they are informed by specific demographic backgrounds and are characterized by aligned goals, motivations, and behavior patterns. This method serves as an effective strategy to structure, prioritize, and direct product experiences intuitively.
