React Native Developer — Voice AI App (iOS & Android)

I'm building VOLT — a voice-first AI app for tradespeople (plumbers, electricians, HVAC technicians) in the US market. The concept is simple: the tradesperson presses record, speaks about their job, and VOLT automatically generates professional documents — invoices, quotes, work orders, parts lists, and job notes — using OpenAI Whisper for transcription and GPT-4 for extraction and document generation. The full prototype is already designed in Superapp (no-code). I need a React Native developer to build the real app for iOS and Android and get it to TestFlight. What needs to be built: Voice recording screen with OpenAI Whisper API integration (audio transcription) GPT-4 API integration to extract job details and generate 5 document types Document viewer screens (invoice, quote, work order, parts list, job notes) PDF generation and native share sheet Jobs tab, Docs tab, Earnings tab with demo data In-app subscription paywall via RevenueCat ($19.99/month or $149/year) Onboarding flow (trade selection, business details, rates setup) Settings screen Tech stack: React Native (iOS + Android) OpenAI Whisper API + GPT-4 API RevenueCat for subscriptions Node.js backend for API calls PDF generation library What I will provide: Full prototype walkthrough (Superapp) Screen-by-screen design spec All demo data, copy, and document templates Clear communication and fast decisions What I need from you: Proven React Native experience with published App Store / Google Play apps Previous experience integrating OpenAI or similar AI APIs Clear communication and weekly progress updates Please include links to 1–2 relevant apps you have built when applying. Applications without examples will not be considered.
