HaruBag - Smart Nappy Bag Checklist

My role

Freelance Project, Design + Development (Claude Code)

The problem

Packing a nappy bag for an outing is deceptively complex. The right items depend on destination, weather, baby's age, and how long you'll be out. Generic checklists don't cut it.

What I did

Designed and built a mobile app that generates a personalised packing list based on those exact inputs, including real-time weather. Built entirely solo using Claude Code from idea to App Store in one sprint. Available in English and Korean.

Why it matters

Proof that a designer with the right tools and a clear problem can ship a real product alone. 5 stars on the App Store.
