I need a full-featured WayFinder application whose core job is to provide clear navigation and directions. The experience has to work seamlessly from the moment a guest approaches a large resort or corporate building all the way to the exact indoor room they are trying to reach, so the routing engine must understand both outdoor pathways and indoor floor plans. Key requirements • Accurate turn-by-turn guidance for cars or pedestrians up to each venue’s main entrance, then smooth hand-off to indoor routing once inside. • Support for multi-level maps, lifts, escalators and stairs so users can move floor-to-floor without confusion. • Venue database built around buildings and resorts; future expansion to other location types should remain possible. • Real-time positioning via GPS outdoors and Bluetooth-based or similar techniques indoors. • Search, favourites and smart re-routing when the user strays off course. • Clean admin interface so I can upload or edit new floor plans myself. I’m open to the stack that makes this most reliable—Mapbox, Google Maps SDK, Leaflet, or any solid indoor mapping toolkit will work as long as the final app ships on both iOS and Android and runs smoothly. Deliverables will be: 1. Interactive prototype showcasing outdoor-to-indoor hand-off. 2. Production-ready mobile apps with source code and build instructions. 3. Lightweight CMS or script for ingesting new venue maps. 4. Clear documentation and a brief hand-over session. If you have already tackled mixed indoor/outdoor routing, beacon integration or large-scale venue mapping, I’d love to see a quick demo link alongside your bid.
