I can analyze it and provide you better solutions and can start working immediately.
To fix some issues, kindly share your existing website URL.
I have different specializations.:
1. Open Source CMS (Wordpress, Drupal, Angular, Joomla, Shopify, Magento)
2. MVC Framework (Laravel, CakePHP, Yii, Codeignter)
I have recently created these websites and providing support and maintenance on many of those applications.
