I need an experienced Laravel/PHP developer to upgrade my existing CodeCanyon multi-service marketplace app. The current stack: · Backend: Laravel 11 Admin Panel · Frontend: 2 Flutter Mobile Apps (User & Provider) · Database: MySQL Core Tasks: 1. Laravel Framework Upgrade (11 → 12): · Update composer.json to require laravel/framework:^12.0 · Run compatibility checks (Laravel 12 requires PHP 8.2+ and Carbon 3) · Test all core functionality post-upgrade 2. CodeCanyon Updates: · Access the latest app code from CodeCanyon · Merge new features with our existing custom modifications · Ensure all third-party packages are compatible with Laravel 12 (check Filament, Spatie, etc.) 3. Git Implementation: · Initialize Git repository for proper version control · Document branching strategy and workflow 4. Server Deployment (Subdirectory): · Install updated code in a new subdirectory on existing server (e.g., /domain.com/new-version/) · Configure web server to run both versions side-by-side · Ensure environment configs are properly set 5. Database Migration: · Copy existing production database · Run Laravel migrations for any new schema changes · Verify data integrity and relationships 6. Testing: · Run php artisan test for unit/feature tests · Verify Flutter apps connect to updated API endpoints · Check all marketplace functionalities (user auth, provider workflows, payments)
