Hi, I want to proceed with the backend development under the following structure and standards: 1. Code Ownership: * The source code must be hosted in a GitHub repository under my account/organization. * You will be added as a collaborator only. * All code must be pushed continuously (no final ZIP delivery). 2. Infrastructure Ownership: * Cloud server, database, and domain accounts must be under my ownership. * You may access them as a developer. 3. Project Structure: * Clean architecture (routes, controllers, services, models, middlewares, config). * Environment variables must be used (.env), and an env.example file must be provided. * No secrets or API keys should be committed to the repository. 4. Documentation: * README with setup instructions. * Swagger (OpenAPI) documentation. * Postman collection for testing. 5. Milestone-Based Delivery: We will divide the project into clear milestones: * Milestone 1: Auth + Roles + Organization (multi-tenant ready) * Milestone 2: Bookings CRUD + Database schema * Milestone 3: Commission logic * Milestone 4: Dashboard APIs (stats & reports) * Milestone 5: Deployment + backups + monitoring Each milestone will be reviewed and tested before payment. 6. Multi-Tenant Requirement: The system must be designed as multi-tenant from day one. All major entities must be linked to an organization/company ID.
