Lesson

Topic: Qubely Global — Web Developer / Engineer (PHP Laravel) (Application Deadline: 28 Apr 2025)

Learning Outcomes

• Identify the key requirements and responsibilities for a PHP Laravel developer at Qubely Global.
• Explain core technologies: PHP (Laravel), HTML5, CSS3, JavaScript/jQuery, MySQL, RESTful APIs.
• Apply best practices for version control, deployment, and third-party integrations.
• Prepare a concise portfolio or GitHub presentation suited to the role.

Conceptual Explanation

Qubely Global is seeking developers capable of building scalable web applications using the Laravel framework. Laravel offers MVC architecture, routing, ORM (Eloquent), middleware, and built-in security features — tools that speed development and encourage maintainable code. Front-end skills (HTML5, CSS3, JavaScript/jQuery, Bootstrap) ensure responsive, accessible user interfaces. MySQL and RESTful APIs are central for persistent data and integrations; understanding JSON, AJAX and API consumption is essential for modern single- and multi-page applications. Version control (Git) enables collaboration, branching and deployment workflows. Optional knowledge of modern reactive tools (Vue.js, React, Livewire) gives candidates an edge for interactive UI components. Employers value problem-solving, independence, and timely delivery as much as technical ability.

Descriptive

1. Describe a typical deployment workflow for a Laravel application destined for a VPS or cloud server.
   Answer

   A typical deployment workflow includes: merging tested code into a release branch, tagging a release, running CI/CD pipelines to build assets (npm/webpack), running composer install --no-dev, migrating and seeding databases if needed (php artisan migrate --force), clearing and caching configuration and routes (php artisan config:cache, php artisan route:cache), transferring files to the VPS or using git pull, setting correct file permissions for storage and bootstrap/cache, and restarting queue workers and web services. Backups and monitoring are part of post-deploy checks.

Creative

1. Propose a two-week learning plan to upskill from general PHP knowledge to being productive with Laravel for a small project.
   Answer

   Week 1: Day 1–2: Install Laravel, learn project structure, routing, controllers, views. Day 3–4: Study Eloquent ORM, migrations, and simple CRUD operations. Day 5: Forms, validation, and authentication scaffolding. Weekend: Build a small CRUD app (e.g., task manager). Week 2: Day 6–7: RESTful API creation, resource controllers, and API authentication (sanctum/passport). Day 8: Front-end integration with Bootstrap and AJAX. Day 9: Testing basics (feature and unit tests). Day 10: Deployment basics, environment config, and security best practices. Final weekend: Polish project, document README, push to GitHub, prepare a short demo and portfolio entry.

Activities, Vocabulary, Homework, Practice Task

Activities

• Pair-program a RESTful endpoint implementing CRUD with Laravel and MySQL.
• Refactor an existing jQuery-driven widget into a small Vue or Livewire component.

Answer

Activity outcomes: Working endpoints, mergeable pull requests, and a demo of front-end component integration.

Vocabulary

• MVC — Model-View-Controller
• ORM — Object-Relational Mapping (Eloquent)
• RESTful API — Representational State Transfer style services
• Middleware — Request filtering layer in Laravel

Answer

Understanding these terms helps in reading docs, interviewing, and communicating within a dev team.

Homework

1. Prepare a one-page portfolio entry for a past project showing GitHub link, tech stack, and your role.
2. Implement a small API in Laravel that returns paginated resource data and document the endpoints.

Answer

Homework evaluation: Portfolio should highlight responsibilities and results; API should include sample requests and responses (JSON) and basic tests.

Practice Task

Deploy a simple Laravel app to a free-tier cloud instance or cPanel and provide deployment notes (commands, environment setup, common pitfalls).

Answer

Practice checklist: composer install, .env configuration, encryption key (php artisan key:generate), database setup, migrations, permissions for storage and cache, queue worker setup (if used), and web server config (NGINX/Apache). Record steps as a guide.
