Overview
CarDieJia is a parking + indoor mall-navigation app designed as a pitch-ready offering for large facility clients. Mockups throughout use "Radiant Plaza" as a de-identified stand-in for the actual anchor-tenant pitch case. It bundles vehicle-locator, online payment, membership rewards, IMDF-powered indoor wayfinding, AI shopping concierge, and store discovery into a single modular app that can be themed per client. I designed the full product as Product Manager and UI/UX Designer.
The full click-path through the pitch case, shown on the de-identified "Radiant Plaza" theme: themed home, store detail on the IMDF map, turn-by-turn wayfinding, and an AI concierge layered on top.
Challenge
Large mall operators have two disjoint customer problems that usually live in two disjoint apps. On the driver side: finding a parking spot, paying without queueing at the kiosk, and getting a reason to return. On the visitor side: navigating a multi-level venue with hundreds of stores, finding a specific brand, and planning a route across the mall. Operators want a single customer-facing surface that covers both, with their own brand painted on top — not a white-label template, not five separate SDKs. A single codebase needed to serve multiple anchor-tenant clients with distinct theming without fragmenting the design.
Approach
- Designed a modular UI system with a shared component library and theming layer that can be customised per client without forking the design — the anchor pitch case (shown here as "Radiant Plaza") was the first applied theme.
- Integrated IMDF-powered indoor wayfinding (leveraging the same IMDF pipeline built at Spatial Topology) so visitors could search a store and see a turn-by-turn route across floors.
- Added an AI shopping concierge on top of the IMDF graph — natural-language queries ("where can I buy a gift under NT$2,000?") resolve to stores, opening hours, and a walkable route.
- Streamlined the vehicle-locator and online-payment flows to remove the two biggest parking-side friction points.
- Added a membership rewards layer to incentivise repeat visits, with states operators could configure without engineering help.
- Leaned the overall look toward a cleaner, enterprise-ready feel to support sales conversations with prospective facility clients.
Results
- Delivered a modular design system that themes per client from a single codebase.
- Packaged hi-fi mockups and full user flows for the anchor-tenant pitch, bundled with IMDF-powered indoor navigation and an AI concierge as differentiators.
- Handed off as a pitch-ready concept at my departure from Spatial Topology — subsequent client traction sat outside my tenure.
