Apptixx Pty Ltd — MPX Client Portal (Phase 1 Development) Ownership: All code, architecture, and IP produced under this contract will be fully owned by Apptixx Pty Ltd, with unrestricted rights to commercialise, resell, white‑label, or license the platform. 1. Project Overview Apptixx Pty Ltd is developing a modular, enterprise‑grade platform designed for the construction, design, and real estate sectors. This project represents Phase 1 — the creation of a core client portal that will act as the central hub for all future modules. The platform must be built with scalability, modularity, and multi‑tenant capability in mind, as future modules (quoting, contracts, compliance, payments, AI tools, etc.) will be integrated into this core. 2. Objective of Phase 1 Develop a secure, modern, responsive client portal that allows different types of clients to track the lifecycle of their project. Phase 1 includes three lifecycle types: A. Construction Project Tracking Clients can view: Project stages Status updates Documents Stakeholders involved Timeline view B. Design Project Tracking Clients can view: Concept → Drafting → Revisions → Approvals Status updates Document hub Comments/notes C. Real Estate Sales Tracking Clients can view: Appraisal → Listing → Marketing → Offers → Contract → Settlement Status updates Document hub Agent notes (read‑only) 3. Core Requirements (Phase 1) 3.1 User Authentication & Roles Secure login (email + password, OAuth optional) Multi‑tenant structure (each business has isolated data) Role-based access control (RBAC) Ability to add future attribute-based access control (ABAC) User types (Phase 1): Client (end user) Internal admin (Apptixx) Project owner (builder/designer/agent) 3.2 Client Dashboard A unified dashboard showing: Active projects Project type (Build, Design, Real Estate) Current stage Notifications Quick links to documents 3.3 Project Lifecycle Engine Each project type must have: A defined set of stages Ability to update stage status Timestamped history Notes/comments Stage descriptions Future‑ready API endpoints for automation 3.4 Document Hub Each project must include: Secure document upload Version control File preview (PDF/images) Permission-based visibility Categorisation (plans, approvals, contracts, reports, etc.) 3.5 Notifications Email notifications for stage changes In‑portal notifications Future‑ready for SMS integration 3.6 Admin Panel (Basic) Apptixx internal admin must be able to: Create/edit/delete projects Assign project owners Manage clients Manage lifecycle stages Upload documents 4. Technical Requirements 4.1 Preferred Tech Stack To ensure scalability and future modular expansion, the preferred stack is: Frontend React or [login to view URL] TailwindCSS or MUI Backend Node.js (NestJS preferred) REST API (GraphQL optional) Database PostgreSQL Prisma or TypeORM Infrastructure AWS (ECS/Lambda, RDS, S3, CloudFront) OR developer may propose equivalent cloud architecture Authentication Auth0 or AWS Cognito (preferred) JWT-based session management 5. Deliverables (Phase 1) Fully functional client portal Three lifecycle modules (Build, Design, Real Estate) Document hub Admin panel (basic) Role-based access Responsive UI API documentation Deployment to staging environment Source code + documentation All IP assigned to Apptixx Pty Ltd 6. Future Modules (Not Included in Phase 1, but Platform Must Support) Developers must architect the system to allow future modules to plug in: Quoting engine Contracts engine Compliance engine payments Subcontractor marketplace Merchant integrations AI-driven document interpretation AI-driven scope generation Multi‑stakeholder permission matrix These are not part of this job but must be considered in the architecture. 7. Developer Requirements Experience building SaaS platforms Strong React + Node.js + PostgreSQL background Experience with multi‑tenant systems Experience with role-based access control Experience with AWS deployment Clean, modular code structure Ability to work with future microservices 8. Engagement Model Fixed price for Phase 1 Milestone-based payments Weekly progress updates Code reviews required All code committed to the Apptixx-owned Git repository 9. Intellectual Property All deliverables, source code, architecture, and related assets produced under this contract become the exclusive property of Apptixx Pty Ltd, with full rights to: Resell White‑label License Modify Commercialise No third-party ownership or licensing restrictions may be applied.

I can help with this, I will build the Phase 1 portal using NestJS with PostgreSQL and React, structured around multi-tenant architecture with row-level tenant isolation and RBAC from day one. The three lifecycle modules (Build, Design, Real Estate) will share a common stage engine with configurable steps per project type, so adding future modules plugs into the same pattern without restructuring. For multi-tenancy, I recommend row-level isolation with a tenant_id on every table rather than schema-per-tenant. This keeps the database manageable at scale while enforcing strict data separation, and Prisma handles it well with middleware-level filtering. Questions: 1) Will Auth0 or Cognito be the choice, or should I evaluate both and recommend? 2) Do project owners need to update stages themselves or will that stay with Apptixx admin for Phase 1? 3) For the document hub, is there a file size or storage limit per tenant you want enforced? Let us discuss via chat. Best regards, Kamran

I’ve helped build multi-tenant SaaS platforms with modular project tracking for construction and real estate clients before, focusing on clean role-based access and secure document handling. For Phase 1, I’ll design a scalable architecture that separates each tenant’s data fully while enabling smooth addition of lifecycle modules later. To cover the three lifecycle types, I propose creating reusable stage and status management components backed by timestamped histories and comments. The document hub will support secure uploads with versioning and fine-grained permission control to keep sensitive plans and contracts safe. Is OAuth mandatory now, or can it be added in a future phase? Also, would you prefer a REST-first backend with REST plus future GraphQL layering or a GraphQL-based API from the start for flexibility? I’ll prioritize simple, responsive React UI using Tailwind for fast iteration and deploy on AWS with an authentication system like Cognito to meet your security needs. Weekly updates and code reviews will keep the project transparent. Ready to start building a solid foundation for your client portal that scales as your platform grows.
