Multipark

Multipark is the parking marketplace of the Multigroup ecosystem: drivers compare and book spaces near airports and city centres, and operators rent out the spaces they have empty.

I designed the backend from the service boundaries up — how the parking, pricing, availability and reservation domains talk to each other — and then implemented it. The same work covers the shared Multigroup authentication and the integration between the group’s services.

The platform runs in production for Lisboa, Porto and Faro, with web and mobile clients (iOS and Android) on top of the same API.

• Service architecture and communication protocols across the platform.
• Shared authentication and integration between Multigroup services.
• Parking, availability, pricing and reservation domains modelled end to end.
• One API serving the website, the iOS app and the Android app.
• Code reviews and documentation that kept the platform maintainable after handover.

• Live at multipark.app with 33+ car parks, 5.000+ spaces and 100+ EV charging stations.
• Handles the booking volume of a business that processes millions per month.
• Also powers the Multigroup service integration and auth layer.
