MediBookHome – Full-Stack CRM & Flutter Mobile Apps Development

# Senior Full-Stack + Flutter Developer Required – Next.js / Turborepo CRM Platform

We are looking for a highly experienced Senior Full-Stack Developer / Software Architect to complete an existing multi-tier healthcare and CRM platform.

This is NOT a project from scratch. A significant portion of the web application, architecture, database, UI, APIs, authentication, CRM modules, and core workflows has already been developed.

We need a senior developer who can understand the existing codebase, perform a complete technical audit, identify gaps, complete all pending features, develop two Flutter mobile applications, integrate all systems, perform end-to-end testing, and take the complete platform to production.

The project will be considered complete only after the web platform and both mobile applications are fully functional and deployed.

## EXISTING WEB ARCHITECTURE

* Turborepo
* pnpm workspaces
* Modular package architecture

### Frontend

* Next.js 14
* App Router
* React 18
* TypeScript

* Radix UI
* class-variance-authority
* lucide-react
* Google Maps using @react-google-maps/api

### Backend / API

* Next.js API Routes / Route Handlers
* No separate backend server
* Vercel deployment
* JWT authentication
* jsonwebtoken
* jose
* bcryptjs
* AWS S3

## END-TO-END WORKFLOW

The complete system must work as one integrated platform:

User App
→ Backend/API
→ Database
→ CRM/Admin
→ Partner App
→ Payment
→ Notifications
→ Storage
→ Booking/Service Workflow

For example, a booking created from the User App must correctly flow through the backend and CRM, reach the appropriate partner, and allow the partner to complete the service. Status, payment, notifications, documents, cancellations, refunds, and earnings must remain synchronized.
