Trip Planner
Less coordination. More going places.
Bring an itinerary, a group, and the shared expenses into one place. A collaboration problem turned into a practical planning tool.
The problem
Trip plans become scattered across messages, lists, and spreadsheets. Groups need a shared plan with clear permissions and room for change.
What I built
- Built trip creation and day-by-day itineraries with activity reordering.
- Implemented trip-specific owner, editor, and viewer roles, invitations, and comments.
- Added checklists, attachments, expenses, and budget reporting.
Inside the engineering
The trip is the collaboration boundary
Invitations, comments, permissions, and planning data are organized around a specific trip.
Planning beyond the itinerary
Checklists and shared expenses keep practical coordination beside the day-by-day plan instead of separating it into disconnected tools.
What this demonstrates
Shows product thinking across collaborative workflows, access roles, and connected full-stack features.
