Hello Friend,
Hope you are very well.
My name is Rohit and I have working experience of Web Development from last 4.5 years. I have worked in Laravel, Codeignter, Symfony, Wordpress and Magento.
As per your job post, it seems that you have a school management system with ACL (for role and its accessibility) integration. Now you have an requirement where you need to provide a special permission for teacher, manger or teacher assistant.
I can help you to complete your requirement with proper approach with following existing system. Thus it will be error free and will be secure & reliable.
Thanks and looking to have a positive response from your side.
