I’m building a mobile-first experience that lets visitors locate any corridor, shop, or facility inside a multi-level venue and receive precise, turn-by-turn guidance. The core of the project is a high-fidelity 3D map that feels as smooth as the navigation systems you find in major malls. Here’s what I need created and integrated: • A detailed, multi-floor 3D map with interactive zoom, tilt, and rotation • Real-time indoor routing that updates with every step • A shop dashboard where tenants can log in, manage their profile, and handle subscription payments • A clean, modern UI that ties everything together on iOS and Android You’re free to work in Mapbox, Unity 3D, Three.js, or an equivalent stack—whichever delivers the most fluid 3D performance on mobile. Respect for deadlines and rapid, clear communication are essential; I’m happy to structure the engagement as either a fixed-price delivery or a longer-term partnership once we click. Please share links or builds of indoor mapping projects you’ve already completed. After reviewing your work, I’ll walk you through the full concept, floor plans, and data layers under NDA so we can scope milestones together.
