I’m building a mobile service that lets cancer patients quickly obtain a second medical opinion. On both iOS and Android, a patient will sign up with simple phone-number verification, upload every investigation image they already have, and watch our AI module automatically place those images in perfect chronological order. From the doctor’s side, the clinician will open the arranged case file, review it, and return a written opinion that is delivered to the patient as a downloadable PDF. The PDF must also embed objective evidence—reference images, guidelines, or citations—so the patient understands why a particular treatment path is recommended. Here’s what I need from you: • A production-ready Android and iOS app, built from a single codebase if possible for efficiency • Secure image upload, compression, and encrypted cloud storage • AI-based chronological sorting (our model is ready; you’ll connect to it through an API) • Automatic PDF generation with embedded evidence links or images • Clean, intuitive UI/UX for patients and doctors, including dark mode • Phone number sign-up / log-in with OTP verification • Admin dashboard or lightweight backend where I can manage users and monitor AI processing queues • Full hand-over of source code, build scripts, and brief technical documentation has payment source also Acceptance criteria: the apps install without errors, a mock patient can upload at least 50 images in one session, the AI returns a correctly ordered timeline within two minutes, and the generated PDF opens on standard readers with all images intact. If you have experience in HIPAA-compliant storage, Flutter or React Native, image processing, and dynamic PDF creation, I’d love to see your approach and timeline.

From developing complex solutions to managing live apps with thousands of active users, I've gained the experience and skills perfectly suited for your Cancer Second-Opinion Mobile App. As a full-stack mobile developer specializing in Flutter and React Native, I can build a single codebase app for both iOS and Android ensuring cost-effective and seamless performance across platforms without sacrificing quality. Security is paramount in your project, and my extensive experience with HIPAA-compliant storage and encrypted cloud storage systems ensures your users' sensitive medical data remains private and protected. Additionally, my proficiency in image processing will guarantee the upload, compression, and sorting of medical images - a critical aspect of providing accurate second opinions. One of the unique features you require is an AI module for chronological sorting. I've connected numerous apps to external APIs before and I am confidently equipped to integrate your existing model into the app. My previous works also demonstrate my ability to create dynamic PDFs with embedded evidence links/image citations which ensures transparency plus clear communication between doctors and patients. So, if you're seeking a seasoned professional that will optimize performance while ensuring adherence to health regulations, I'm your best bet!

The trickiest part of this isn't the app itself, it's making sure 50+ high-res medical images upload reliably on spotty hospital Wi-Fi without killing the user experience. I'll build this in React Native with chunked, resumable uploads so nothing is lost mid-session. I'll wire up your AI sorting API, handle OTP auth via Firebase, and generate the PDF with embedded evidence using react-native-pdf-lib. One thing worth flagging: for HIPAA-compliant storage, you'll want encrypted-at-rest buckets with signed URLs that expire, not direct links. I've set this up before and it's straightforward. 1) Is your AI sorting API hosted already, or do you need me to deploy it as well? Happy to talk details in chat. Shayan

You need AI-sorted case file review with auto-generated evidence PDFs, built as a single React Native codebase across iOS and Android with a clean doctor/patient split UX — that's exactly the kind of medtech stack we've shipped. We've built patient-data apps with OTP authentication, secure image uploads to encrypted cloud storage, and AI API integration for clinical decision support. PDF generation embedding reference images and citations is straightforward with the right library combination. Happy to walk through our approach to the AI chronological sort API integration and the secure storage architecture. Ping us.

This project involves much more than building a mobile app—it requires a secure workflow that moves patients from image upload to AI-assisted case organization and finally to a clear, evidence-backed medical report. The architecture needs to handle large image uploads, reliable AI integration, and protected medical data while keeping the experience simple for both patients and doctors. I would recommend Flutter for a single codebase targeting iOS and Android, backed by secure APIs and encrypted cloud storage. The app would support OTP authentication, batch image uploads with compression, AI timeline integration, doctor review workflows, payment integration, and PDF generation with embedded reference images or citations. An admin portal would provide user management, AI job monitoring, and operational visibility. The system would be designed with scalability, security, and maintainability in mind, along with comprehensive handover documentation. I have experience building full-stack mobile applications with secure authentication, API integrations, cloud services, and document generation. My focus would be on delivering a reliable platform that can evolve as your AI models and clinical workflows grow. One question: do you already have the backend APIs for authentication, payments, and doctor management, or should those be developed as part of this project? Jaroslav Caprata

Your project requires more than a simple mobile app because the critical parts are reliability, secure medical data handling, upload performance, and a workflow that remains fast even when patients submit dozens of investigation images in a single session. My approach would be to build the application with a shared mobile codebase (React Native or Flutter depending on your preference) connected to a scalable backend responsible for authentication, image processing orchestration, PDF generation, and AI integration. The upload flow would include image compression, resumable uploads, encrypted cloud storage, and asynchronous processing so the timeline ordering remains responsive even with large image batches. For the doctor workflow, I would structure the case timeline around normalized metadata and AI ordering results, making the review interface clean and efficient. The PDF generation layer would support embedded reference images, citations, and evidence sections while preserving compatibility with standard PDF readers. The backend architecture would also include: - OTP-based phone authentication - Processing queue monitoring - Role separation for patients, doctors, and admins - Secure API integration with your AI service - Logging and auditability for medical workflows - Cloud deployment with scalable storage and processing I can deliver the complete source code, deployment scripts, API documentation, and handover documentation. Estimated timeline for an MVP with production-ready foundations is approximately 6 to 8 weeks depending on final UI scope and compliance requirements.
