Comprehensive Mobile App Development

Design mobile app on different subjects and done following jobs
1. Code review & stabilization — audit the existing React codebase, fix bugs, clean up architecture where needed
2. Production hardening — proper environment config, error handling, performance optimization, mobile responsiveness testing
3. Backend/data layer — set up or review database, user auth, and data storage for tracking features (kick counter, contraction timer, health monitors)
4. AI doctor chat — ensure reliable, production-grade integration (API key handling, rate limits, fallback behavior)
5. Payment integration — implement one-time purchase flow for individual premium tier (per our pricing strategy — no subscription model)
6. QA & testing — cross-browser and cross-device testing, especially mobile (majority of target users on phones)
7. Public launch — domain setup, hosting, app store considerations if a wrapped mobile app is desired, analytics integration
8. Documentation — basic technical handover docs for future maintenance

What We Need From Applicants
