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 Ability to deliver a TestFlight build within 8–10 weeks 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.
