Building a design system, recommendation engine, and 19 screens for a concept that had the vision but not the structure.

Moonbrew s a specialty coffee shop where your drink is chosen by the stars. Literally. The owner wanted a mobile app that captures your birth chart data, reads the current lunar phase, and recommends a personalized beverage.

The design problem: how do you ask for birth date, birth time, and birth place without it feeling like a medical form? How does a "cosmic recommendation" lead to an actual purchase? And how do you build a loyalty system around moon phases that works for someone who doesn't care about astrology?

The starting point was two concept documents with the product vision. From there, I defined the wireframes, user flows, screen inventory, and recommendation logic that the project needed to move forward.
