Ombak
Surfboard sharing for Canggu
🚧 In progress WhatsApp-powered Market: Bali

A surfboard sharing app built for the Canggu surf scene. Instead of buying a board for a few weeks, rent one from a local — all coordinated through WhatsApp. Built using Claude Code and Claude Design. My first real product, being shipped in public.
