Mobile Development React Native

React Native Developer — Safety Training App (iOS + Android) — Fixed Price $8,000 I'm building a OSHA-compliant safety training mobile app for construction contractors. The app delivers video-based training modules, enforces completion before unlocking quizzes, generates branded PDF certificates, and maintains a full audit log of worker completions. This is a well-scoped, fixed-price project with a locked feature set. I am not looking for hourly work or scope expansion — I need a developer who can execute a defined spec and deliver on an 8-week timeline. — WHAT YOU'LL BUILD — • React Native app (iOS + Android) — must ship to App Store and Google Play • Vimeo API integration — embed videos, track watch percentage server-side, gate quiz until 85% watched • 8-module sequential training flow — each module locked until prior module passed • Quiz engine — randomized question banks, 80% pass threshold, retake rules • Supabase backend — auth, database, audit log with timestamps • PDF certificate generator — branded, unique cert ID, worker name, expiration date • Admin dashboard — view all workers, completions, scores, export records per employer — REQUIRED SKILLS — • React Native (must show shipped App Store apps — send links) • Supabase or comparable backend-as-a-service • Vimeo API experience (watch percentage tracking preferred) • PDF generation in mobile/server context • Apple App Store + Google Play submission experience — HOW TO APPLY — To be considered, answer these three questions in your proposal: 1. Send App Store or Play Store links to two React Native apps you've shipped 2. Have you used the Vimeo API to track watch completion? If yes, briefly describe how 3. What is your biggest risk to an 8-week timeline for this project and how would you handle it? Proposals that do not answer all three questions will not be reviewed. Budget: $8,000 fixed price, paid in milestones Timeline: 8 weeks to App Store submission
