React Native / Expo + AWS Developer to Help Prepare Kairos for Launch

We're looking for an experienced freelance developer to help our current developer get Kairos across the finish line. This is an existing coaching app with a React/TypeScript website, Expo/React Native mobile app, and AWS backend. Stack: React, TypeScript, Vite, Expo, React Native, Cognito, Lambda, AppSync/GraphQL, DynamoDB, Bedrock, and AWS CDK. Payments use Stripe and native store subscriptions. Initial budget: $300 fixed-price for a launch-readiness assessment, a handoff call with our current developer, and a prioritized list of blockers with recommended fixes and estimates. Any implementation work will be scoped and agreed separately. Assessment deliverables: 1. Review the codebase and meet with our current developer. Provide a short map of the web/mobile environments and deployment process. 2. Assess mobile build/backend alignment, existing test execution, authentication, subscriptions, and release configuration. Identify what is verified and what still needs testing. 3. Deliver the top three launch blockers with evidence, recommended fixes, and effort/cost estimates. 4. Provide a concise handoff and launch-readiness recommendation. This engagement is assessment only. It does not include a rebuild, implementation fixes, or a guaranteed complete launch for $300. Relevant experience: shipping Expo apps through TestFlight, AWS serverless backends, Cognito authentication, Stripe or native subscriptions, and Playwright or Maestro testing. Please include: - One relevant app or project and your specific contribution. - Your Expo/React Native and AWS experience. - Your approach to the assessment, confirmation that you can complete it for $300 fixed-price, and your availability. We value clear communication and collaboration with our current developer. Repository details will be shared privately with shortlisted candidates. No production changes are included in this assessment.
