ParKings is a fully built, production-ready real-time marketplace platform originally developed for parking, with the infrastructure to connect users with location-based inventory, real-time availability and reservations. ParKings has been selected as one of the 100 Best Innovative Technologies for International Cooperation at the ZGC Forum 2025 in Beijing The platform includes 8 active repositories covering the Java/Spring Boot backend, React Native iOS & Android application, TypeScript web client, business-facing website, shared UI library and deployment infrastructure. Core technology includes: • Real-time WebSocket architecture with area-based geographic subscriptions • PostgreSQL + PostGIS geospatial search and spatial queries • Full booking and reservation engine for on-demand and scheduled reservations • Host approval, inventory management and cancellation flows • Real-time availability and reservation state propagation • Docker-based deployment configuration • Complete database schema and WebSocket API documentation The backend contains approximately 30KB of production booking/business logic, while the overall platform represents an estimated 12–18 months of equivalent development work. The sale includes the complete source code, database schema, API documentation and deployment configuration. The IP is clean, with no investor entanglements or revenue-share obligations. Parking is the original use case, but the underlying architecture can be adapted to other location-based marketplaces involving physical inventory, availability and reservations. Pre-revenue and available for acquisition. Selected technology components may also be considered separately. NDA available before repository access.
