The challenge
Harbor needed a consumer money app that felt instant and trustworthy — offline-tolerant, secure, and simple enough for first-time users to move money without a second thought.
What we did
We designed an offline-first architecture with optimistic UI, built native modules for the sensitive flows, and shipped a design system so Harbor's own team could keep moving fast after launch.
