🎯 Your Mission

Build the core foundation of a scalable Mini-LMS.

🧰 Tech Stack

1. Laravel 11/12

2. Livewire v3

3. Alpine.js

4. Filament v3

5. Pest

6. MySQL

7. Plyr.js

8. Docker + Docker Compose (Required)

📌 Core Functional Scope (Focused)

1️⃣ Public Home

1. / lists published courses (title, image, level)

2. Must be efficient (no N+1)

2️⃣ Authentication & Enrollment

1. Registration sends Welcome Email (queued/async)

2. Enrollment requires authentication

3. Enrollment must not create duplicates

4. Enrollment must not allow draft courses

5. System must behave correctly under:

   1. rapid clicks

   2. network retries

   3. queue retries

3️⃣ Course View

/courses/{slug}

1. Course details

2. Ordered lessons

3. Free preview lessons accessible to guests

4. Unique slug handling (including soft deletes)

4️⃣ Lesson & Progress

/courses/{slug}/lessons/{lesson}

1. Video player via Plyr

2. Mark as completed

3. Track started_at, completed_at

Completion rules:

1. A course becomes completed when all required lessons are completed

2. On completion:

   1. Create certificate record (UUID)

   2. Send completion email (async, once only)

Courses may be edited after users enroll (lessons added/removed).
System must remain logically consistent.
(No further clarification will be provided.)

⚡ Required Alpine Behaviors (Min 3)

1. Accordion lesson list

2. Confirmation modal before marking completed

3. Animated progress bar

4. Plyr lifecycle integration

5. (Bonus) Dark mode toggle

🛠 Architectural Requirements

1. Core flows implemented via Action classes

2. Use Events + queued listeners where appropriate

3. Use DB constraints where appropriate

4. Use transactions in multi-step flows

5. Policies must isolate user data and prevent cross-user exposure

🐳 Docker Requirements (Mandatory)

Your submission must include a working Dockerized setup with:

Required services

1. app (PHP-FPM or Laravel container)

2. web (Nginx or Apache)

3. db (MySQL)

4. queue worker (separate container OR same image different command)

5. (Optional bonus) redis for queue/cache

Must-have DX

1. docker-compose.yml at repo root

2. One-command start:

   1. docker compose up --build

3. Documented bootstrap script/commands in README:

   1. install deps

   2. migrations + seeds

   3. queue worker

   4. run tests

✅ The reviewer should be able to run the full project on a clean machine using Docker only.

🧪 Testing (Pest Required)

Must cover:

1. Enrollment integrity (idempotency / duplication prevention)

2. Completion flow integrity (email once + certificate once)

3. Slug uniqueness rule

4. User isolation (policy/access)

5. At least one meaningful edge case of your choice

🧠 Product Thinking Layer 

Note : Please focus on explaining your own thinking and decision-making process. We want to understand how you approach product problems and evaluate trade-offs — this is about your thinking, not AI-generated answers.

In addition to implementation, you must include a section in /docs/PRODUCT_THINKING.md.

In this document, answer:

1️⃣ Business Risks

What are the top 3 product risks in this LMS?

Explain how your architecture supports or mitigates these risks.

2️⃣ Metrics That Matter

If you were working with Product, what 5 metrics would you track?

Explain:

1. Where would you capture these metrics?

2. Would you compute or store them?

3. How would you avoid performance issues?

(No need to fully implement analytics — just design thinking.)

3️⃣ Future Evolution

Imagine in 6 months Career 180 wants:

1. Paid courses

2. Mobile app API

3. Corporate multi-tenant accounts

4. Gamification badges

Explain:

1. What in your current architecture supports this?

2. What would need refactoring?

4️⃣ Trade-offs You Made

List 3 conscious trade-offs you made. And Explain why.

📦 Deliverables

Repo must include:

4. Events + listeners

5. Policies
