React Native Mobile App Developer — Vehicle Inspection App (Android + iOS)

We are a mobile vehicle inspection company scaling nationally. We need a custom inspection app built in React Native to replace our current third-party solution. This app will be used by 1099 independent inspectors in the field. This is a long-term relationship. Phase 1 is the core app. Phase 2 will add contractor management, dispatch, and multi-market features. CORE FEATURES NEEDED: INSPECTION FLOW (most important): - Guided point-by-point inspection — tech cannot skip a step - Each point requires: Photo → Highlight problem area on photo → Grade selection → Notes → Next - Speed dropdown grades: Good / Fair / Poor / Fail / Not Equipped - Pre-saved comment library for fast note entry - 100-point customizable inspection template - Tech literally cannot submit without completing every step VEHICLE INTAKE: - VIN scan (barcode + QR) - VIN auto-lookup via NHTSA free API (returns Year, Make, Model, Engine, Drive Type automatically) - Manual entry fallback - Mileage, color, inspector name, client name fields PHOTO MANAGEMENT: - Vehicle diagram with camera positions (front, rear, driver side, passenger side, undercarriage) - Unlimited photos per inspection point - Photo annotation/highlight tool built in REPORT & EXPORT: - PDF generation on device - Branded report with company logo - Summary chart (Good/Fail/NE counts) - Cloud upload/sync ADMIN PORTAL (web): - View all completed inspections - Download reports - Manage inspectors - Track inspection history per vehicle/VIN TECH STACK REQUIREMENTS: - React Native (Android + iOS from one codebase) - Firebase for cloud sync and storage - NHTSA API for VIN decode (free, no cost) - PDF generation library - Photo annotation library WHAT I WILL PROVIDE: - Full feature spec document - Screenshots of current app for reference - Brand assets (logo, colors) - Inspection point list (all 100 points) - Sample report PDF for design reference TIMELINE: TO APPLY — ANSWER ALL OR WON'T BE REVIEWED: 1.
