Priority bug fixes (8-12 hours) Fix the critical and high priority issues identified in the code review. Likely areas include: - Navigation edge cases - Supabase query optimisation - expo-notifications implementation - Image handling and signed URL patterns - Any crashes or instability found during review 3. EAS Build setup and TestFlight submission (4-6 hours) - Configure eas.json for iOS production build - Set up app signing and provisioning profiles - Build and submit to TestFlight - Resolve any build errors that arise --- About you: - Strong React Native and Expo experience, 3 or more years - Experience with EAS Build and App Store submission specifically - Supabase experience preferred - Available to start within 1 to 2 weeks - Good English communication, daily updates required - Eastern Europe or Latin America preferred for timezone overlap --- Engagement: - Hourly rate, 25 hours maximum - Timeline: 1 to 2 weeks - GitHub repo access provided - All communication via Upwork --- To apply please include: - Your specific experience with Expo SDK and EAS Build - Any similar apps you have worked on - Your availability and estimated timeline - Brief note on your code review approach
