We are looking for a Senior Full-Stack + Flutter Developer or a small experienced development team to complete and take an existing healthcare/CRM platform to production. This is NOT a project from scratch. Approximately 80% of the web platform is already developed using [login to view URL], Turborepo, TypeScript, PostgreSQL, Prisma, Supabase, and existing APIs/CRM modules. Important mobile pages and functionality have also already been created and are currently running through the existing WebView implementation. The first step is to audit the existing codebase, understand what is completed, identify remaining gaps and bugs, and create a practical completion roadmap. The main remaining work includes: • Complete end-to-end booking and scheduling workflows • Verify and complete payment integration, transaction handling, webhooks, cancellations and refunds • Complete Google Maps/location integration • Complete CRM/Admin workflows • Complete partner assignment and service lifecycle • Complete notifications and status synchronization • Fix API, database, authentication and business-logic issues • Complete testing across all critical workflows • Prepare the platform for production ### Flutter Applications The existing mobile functionality currently needs to be separated into TWO proper production Flutter applications: 1. MediBookHome User App For patients/customers — registration, OTP, profile, addresses, service discovery, booking, scheduling, patient details, payment, booking tracking/history, cancellation/refunds, notifications, documents, Google Maps, support and settings. 2. MediBookHome Partners App For nursing staff, lab partners/technicians, doctors, physiotherapists and other healthcare service providers — registration, OTP, profile, KYC/documents, verification, availability, booking requests, accept/reject, assigned jobs, patient details, location/navigation, service status, completion, earnings, payment status, history, notifications, documents, support and settings. The developer should reuse existing working functionality wherever appropriate rather than rebuilding the entire project from scratch. ### End-to-End Requirement The complete workflow must work reliably: User App → Backend/API → Database → CRM → Partner Assignment → Partner App → Service Completion → Payment/Earnings → Notifications → Booking History All data and status changes must remain synchronized across Web, CRM, User App and Partner App. ### Production Deployment The developer will be responsible for final production readiness and deployment, including: • Web/Vercel production deployment • Database/environment configuration • Payment, SMS/OTP, Google Maps and storage configuration • Security and authentication • GitHub/GitHub Actions CI/CD • Android production builds and Google Play submission • iOS production builds and App Store Connect submission • Real-device testing and production debugging ### Required Experience Strong production experience is required with: • [login to view URL] / React / TypeScript • Turborepo / pnpm • PostgreSQL / Prisma / Supabase • Flutter / Dart • REST APIs • JWT/OTP/RBAC • Payment gateways • Google Maps • AWS S3 • Push notifications • GitHub Actions / CI/CD • Vercel • Android & iOS production deployment We are specifically looking for someone capable of taking ownership of an existing complex codebase, understanding it quickly, independently debugging issues, completing missing workflows, and taking the project from its current ~80% state to a stable production release. Please include your experience, similar projects, published Flutter apps, GitHub/GitHub Actions experience, payment/Google Maps experience, availability, hourly or fixed rate, estimated timeline, and number of developers involved if applying as a team. This is a completion and productionization project — not a simple UI development task and not a from-scratch project.

Thank you for considering me for your healthcare/CRM platform project, which requires an experienced full-stack developer with a mastery of [login to view URL], PostgreSQL, and other key technologies including Fluuter.

These projects have given me the chance to hone my skills in debugging, completing missing workflows, and taking projects like yours from their current state to a stable production release. Deploying high-quality applications on time is one of my primary objectives. Your project's existing codebase is not a challenge, but an opportunity for me to leverage my skills in audit and problem solving. I will efficiently identify remaining gaps and bugs and create a practical roadmap so we can move forward effectively together. In conclusion, my passion for technology innovation combined with my commitment to quality will allow us to build scalable and secure healthcare/NRM platform that aligns perfectly with your business goals.

Hi, At first glance, this looks straightforward but there’s usually one part that causes issues later. Happy to share a quick plan if you're open to it. Regards, Rajesh

Hi, Thanks for sharing your project. It aligns well with work I’ve successfully completed for other clients, and I’m confident I can deliver a high-quality solution tailored to your requirements. Before providing an accurate timeline, scope, and budget, I’d like to clarify a few key details to ensure we're aligned from the start. Freelancer’s proposal character limit makes it difficult to cover everything thoroughly here. If you're available, let's connect via chat. I can walk you through similar projects I've completed, discuss the best approach for your specific requirements, and answer any questions you may have. Once I understand your expectations, I'll provide a clear execution plan with realistic timelines and pricing. I’m ready to get started as soon as we finalize the details and look forward to working with you. Best regards, Mayank Sahu

Hi there, I can take your existing healthcare/CRM platform from its current ~80% stage to production. I’ll first audit the codebase, then complete booking, payments/webhooks, Google Maps, CRM, partner assignment, notifications, API/auth issues, and end-to-end testing. I can also convert the existing WebView functionality into dedicated Flutter User and Partner apps while reusing the working code where possible. I’ll handle CI/CD, Vercel/Supabase setup, Android/iOS builds, store submission, real-device testing, and production deployment. Do you already have the GitHub repository and staging access ready for the initial audit? Kindly message me to discuss the roadmap and milestones. Thank you!
