Designing a consumer app that turns every café visit into a collectible stamp, and everyday café-hopping into a ritual worth keeping.

Brewwww! is a drink-logging app for café lovers. Snap your drink, and each visit becomes a collectible vintage stamp marked with the shop, date, and city. It also deepens the connection between drinkers and local cafés: exclusive Shop Stamps reward visiting in person, turning collecting into real foot traffic for the shops people love. What began as a personal habit grew into a worldwide collecting community.

As founding designer, I led the product from first sketch to launch. I set the 0-to-1 direction, defined the design system and brand, and developed an AI-native workflow that paired Claude with Figma to scale the system and close the design-to-dev gap. Beyond the app, I drove the go-to-market and the brand-partnership model that made Brewwww! both a community and a business.

Stamps, three kinds to collect

Part #3 Time Stamps
Auto-created on every check-in, a vintage postmark with the shop, date, and city. Swipe through your collection and the pages turn like a real book.

Part #4 Brewwww! Stamps
Hand-drawn rewards, unlocked at cup milestones and through limited-time events. Tap one and it flips over, then flips back on its own.

Part #5 Shop Stamps
Shop Stamps are exclusive stamps we design for partner cafés, unlocked only by visiting in person. Tap to flip one over, and it turns back on its own.

Part #6 Map
Tap the map button to see every café you've checked in at, pinned from your city to worldwide. Open any pin to see the shop and what you drank there.

Stamps are earned, not bought. Reach a cup milestone to unlock a hand-drawn Brewwww! Stamp, or check in at a partner café in person to unlock its exclusive Shop Stamp.

What started as my own café-hopping habit became Brewwww!, now collected by people across 25+ countries. Building it 0 to 1 as the founding designer is a clear picture of how I work: AI for the repetitive parts, hands and judgment for everything that gives a product its soul.

If you'd like to collaborate, go deeper on the work, or just connect, I'd love to hear from you.
