Senior React Native / Supabase Team for Social Event Platform V1

We are seeking an experienced senior mobile development team to build the production V1 of a verified 18+ social-event discovery and real-world connection platform. This is not an early idea-stage project. Product scope, user journeys, technical requirements, database/API architecture, QA requirements, development milestones, and a detailed RFP have already been prepared. We need a development partner capable of implementing the product securely and challenging technical assumptions where appropriate. PREFERRED TECHNOLOGY • React Native + Expo • TypeScript • Supabase / PostgreSQL • Versioned APIs • Identity and age-verification integration • Mapbox or equivalent geospatial technology • QR + location-based check-in • Push notifications • Real-time data • 1:1 messaging • Secure web-based administration • iOS and Android production deployment MAJOR V1 SYSTEMS The platform includes: • Verified identity and age eligibility • User profiles and preferences • Event creation and venue authorization • Public/private access controls • Protected event locations • Event discovery and recommendations • RSVP, capacity and waitlist management • QR/location-based verified attendance • Real-time attendee-powered event activity • Host and guest reputation systems • Reviews and reporting • Trust & Safety workflows • Connections between attendees • 1:1 messaging • Administrative moderation tools SECURITY & PRIVACY Security and privacy are major requirements. Sensitive functionality such as age eligibility, location access, attendance verification, reputation, real-time event signals and administrative privileges must be enforced server-side. We are particularly interested in teams with experience building: • Social/community platforms • Two-sided marketplaces • Location-sensitive mobile applications • Real-time applications • Identity-verification systems • Trust & Safety systems • High-integrity user-generated systems DEVELOPMENT STRUCTURE The project will be evaluated across seven milestones: 1. Foundation 2. Identity & Events 3. Discovery & RSVP 4. Attendance & Real-Time Event System 5. Trust & Safety 6. Connections 7. Production Readiness Shortlisted candidates will receive a detailed RFP and will be asked to provide milestone-by-milestone pricing, duration, staffing and assumptions. OWNERSHIP REQUIREMENT The client must retain administrative control of the source repository and production accounts. Project-specific code, database schema, APIs, deployment configuration, documentation and related deliverables must be transferable/assignable to the client under the final agreement. TO APPLY Please address the following in your proposal: 1. What production React Native/Expo applications has your team shipped? Describe your role and provide examples that can be independently reviewed. 2. Describe the most relevant marketplace, social, geolocation, identity-verification or real-time platform your team has built. 3. How would you architect a system where a precise event address must remain unavailable to a mobile client until server-side eligibility conditions are satisfied? 4. Who specifically would work on this project? Identify the proposed technical lead, mobile engineer(s), backend engineer(s), QA and DevOps/security resources. 5. Based only on this summary, what approximate budget range and calendar timeline would you expect for a production-quality V1? We understand that your formal estimate may change after reviewing the detailed RFP. Please do not submit a generic agency introduction. We will prioritize applicants who directly address the questions above. We are interested in a long-term technical relationship with the right team, but the initial engagement is the production V1.
