I’m ready to turn HostSwap into a functioning MVP and need a senior Bubble.io expert to take the reins. HostSwap is a non-reciprocal, credit-based exchange where professional hosts — we’re starting with Booking.com and Airbnb.com operators, boutique hotels, apartmant houses, guesthouses, glampings, villas — can fill vacant nights in each other’s properties instead of leaving them empty. The platform will live entirely on Bubble, so please be confident with advanced custom states, API workflows, privacy rules, and responsive design. The interface has to feel modern and sleek, matching the polished look Booking.com hosts already expect. Core build requirements • Multi-unit listings (1–200 rooms per property) • Dynamic credit system (season & category multipliers) • Stripe integration for three subscription tiers plus one-time insurance payments • Bulk ICS/iCal import for calendars • End-to-end booking flow with automatic PDF contract generation • Real-time chat between hosts • Referral logic and onboarding bonus credits Acceptance criteria • All flows above must function in both test and live modes without console errors. • Stripe webhooks correctly create, upgrade, downgrade, and cancel subscriptions. • PDF contracts store in Bubble’s file manager and link back to each booking. • Chat loads instantly and marks messages as read/unread in real time. • Credit calculations match spec across edge cases (e.g., partial stays, high-season multipliers). When you apply, show me your relevant experience and drop links to two or three Bubble marketplace apps you personally shipped. I’ll review qualified candidates this week and move fast if the fit is right.
