PartyHub Rental is a two-sided marketplace for casual event rentals (bounce houses, food trucks, photo booths, etc.).

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.
