Final Project 🏆

Build and deploy a complete PHP web application — TaskFlow, a project management tool with authentication, RBAC, real-time notifications, and a RESTful API.

What You'll Build

• User authentication with JWT, email verification, and password reset
• Project management with team invitations and RBAC permissions
• Task board with drag-drop status, assignees, and file attachments
• Notification system with email, in-app, and Slack integration
• RESTful API with rate limiting, validation, and audit trails

Note: PHP runs on a server. Our examples simulate PHP logic using JavaScript. To run real PHP, install PHP.

🎯 This project combines everything you've learned: OOP (Lesson 11), database design (12), security (13, 24-25), APIs (14, 18, 28), authentication (23), RBAC (42), file storage (43), queues (30), email (31), testing (45), and deployment (47). It's your portfolio piece that proves you can build production PHP applications.

Application Architecture

TaskFlow uses a modular monolith architecture with four core modules: Auth, Projects, Tasks, and Notifications. Each module has its own controllers, services, and models. Modules communicate through domain events — when a task is assigned, the Notification module sends an email without the Task module knowing how notifications work.

Database & Features

The database schema uses proper foreign keys, enums for status fields, and timestamps for audit trails. The feature checklist covers everything a real project management app needs — from user registration to Slack notifications. Build it incrementally: authentication first, then projects, tasks, and notifications.

💡 Building Tips

1️⃣

Start with authentication — Registration, login, JWT tokens, and email verification. Everything else depends on knowing who the user is.

2️⃣

Build the API first — Design your REST endpoints and test with Postman/Insomnia before building any frontend. A solid API is the foundation.

3️⃣

Write tests as you go — Don't save testing for the end. Write a test for each feature before moving to the next one.

4️⃣

Deploy early — Set up Docker and CI/CD in the first week. Deploying a "Hello World" is easier than deploying a full app later.

📋 Quick Reference — Project Milestones

Week	Milestone
Week 1	Auth module + Docker setup + CI/CD pipeline
Week 2	Projects module + RBAC + team invitations
Week 3	Tasks module + comments + file attachments
Week 4	Notifications + search + performance tuning
Week 5	Testing + security audit + production deployment
