The Challenge: High-Stakes Double Bookings During Holiday Surges
Travelers booking airport parking cannot afford to arrive for a morning flight only to find their reserved parking stall occupied. In traditional reservation platforms, race conditions during peak travel holidays often lead to overbooking and stranded passengers.
Parkflyy required a robust platform with atomic inventory locks, automated calendar pricing adjustments based on seasonal occupancy rates, and automated payout disbursement to independent airport parking lot operators.
Technical Architecture: Atomic Slot Allocation & Stripe Webhook Flow
We architected an idempotent booking engine on Node.js and Express, storing capacity matrices in MongoDB with compound indexing across date ranges and lot IDs.
During checkout, a temporary 10-minute hold is placed on the parking stall. Upon receiving a cryptographically verified Stripe webhook, the hold converts into an immutable confirmed ticket with a dynamic QR code for seamless entrance gate scanning.
