Kuji is a shake-to-draw side quest app for iOS. Shaking the phone draws a gashapon-style capsule with a small real-life activity inside — the user can keep it, return it to the jar, or mark it "Lived" once it's done. The app holds 214 hand-curated quests, and Ukrainian, and is built around deliberate restraint: no streaks, no accounts, no coaching, no data collection. The core challenge wasn't only designing the product — it was building it. The entire app is written in SwiftUI and SpriteKit, with no prior Swift experience, using Claude Code as a development pair.

I owned every discipline end to end: product definition, UX and UI, motion and haptics, illustration direction, copy, App Store assets, and ASO. What made this possible wasn't the AI — it was years of working alongside engineers, PMs, and QA, which meant I could write specs, review code decisions, and debug like a teammate rather than a client. Kuji shipped to the App Store as a finished, reviewable product: a designer's judgment carried through every layer, from physics tuning to release notes.
