We are seeking a mobile app developer (React Native / Flutter preferred) to build a working prototype for Project Hammer — a location-based interactive platform. The project already has a defined roadmap, and we are now looking for a developer to create a robust prototype that demonstrates the core functionality.
Core Requirements:
Access system using activation codes to unlock experiences
Ability to support small and large groups (5 to 500+)
Synchronized media playback across devices (audio, video, or images)
GPS/location triggers to launch media content
QR code scanning to progress through different stages of the experience
Group management features, including the ability to split and later rejoin groups
Cloud-based backend for scalability and future expansion
What We Provide:
Wireframes and product roadmap (shared post-NDA)
Creative direction and content (not part of developer scope)
What We Need From You:
Build the prototype from scratch
Advise on best tech stack for scalability
Deliver a stable, working demo app for live testing
