The party rental industry is extremely fragmented. Most vendors rely on phone calls and Facebook pages for bookings. Built this to give both sides a proper platform.
The interesting technical problem was the availability engine. Rental items have constraints most booking systems don't handle well: setup/teardown windows that vary by item, travel radius limits based on vendor location, multi-day bookings, and cascading conflicts when one booking shifts. The calendar logic accounts for all of these to prevent double-bookings and ensure realistic scheduling.
Stack is a standard full-stack web app. Vendor-side has listing management, calendar, and a booking dashboard. Consumer-side has search with filters, comparison views, and direct booking.
Current limitations: category list is fixed for now (bounce houses, food trucks, game trucks, photo booths, general equipment). Vendor onboarding has a manual review step. Payment processing is handled but chargebacks/disputes are still manual.
