Mobile App Developer Needed for a Pet Health & Wellness App (iOS and Android)

I'm looking for an experienced mobile app developer to build a pet health and wellness application that helps pet owners manage their pets' healthcare, appointments, vaccinations, and daily care routines from one place. The goal is to create a practical, easy-to-use mobile app that makes it simpler for pet owners to keep track of important health information without relying on scattered notes, calendars, or paper records. I'm looking for someone who can contribute to both the technical implementation and the product experience, from defining the core app architecture to delivering a reliable, production-ready MVP. Core Features 1. Pet Profiles and Health Records Create profiles for multiple pets, including name, breed, age, weight, and medical history. Store vaccination records, allergies, medications, and veterinary visit details. Upload and organize relevant documents and health records. 2. Appointment and Medication Reminders Schedule veterinary visits and vaccination appointments. Set recurring medication reminders and care notifications. Send timely push notifications and allow users to manage reminder preferences. 3. Health Tracking Dashboard Track weight, medication schedules, vaccination status, and other basic wellness information. Display historical records in a clear, easy-to-understand format. Provide an overview of upcoming appointments and pending care tasks. 4. Veterinary and Clinic Information Allow users to save their preferred veterinary clinics and contact details. Provide a straightforward way to access clinic information when needed. Structure the app so that clinic discovery or appointment booking can be added in a future phase. 5. User Accounts and Data Management Implement secure registration, login, and account management. Support multiple pets under one account. Store user data reliably and provide appropriate access controls. Technical Expectations Experience developing and publishing iOS and Android applications using Flutter, React Native, or native technologies. Strong understanding of mobile UI/UX, API integration, push notifications, and backend communication. Experience designing maintainable backend services and databases. Familiarity with secure handling of personal information and cloud-based file storage. Ability to test across devices, troubleshoot issues, and prepare the application for release. Please recommend a technology stack based on the project's requirements and explain the reasoning behind your choice. What I Expect From the Developer Help refine the MVP scope before development begins. Build a clean, intuitive, and responsive mobile experience. Deliver well-structured, maintainable code. Test the main user journeys, including account creation, pet profiles, reminders, and health record management. Assist with App Store and Google Play submission. Provide source code, setup documentation, and a clear handover. Communicate progress consistently and flag technical risks early. When Applying, Please Include Links to two or three mobile apps you have personally developed, preferably in healthcare, wellness, pet care, or another data-driven consumer niche. Your specific role in those projects and the technologies used. Which stack you recommend for this application and why. How you would implement reliable medication and vaccination reminders across iOS and Android. Your estimated timeline and budget for delivering the MVP. Any important technical or product decisions you would clarify before starting. Please apply only if you have hands-on mobile development experience and can take ownership of the implementation through release. I'm interested in building a dependable product with a strong foundation that can grow through future feature releases.
