Greetings!
My name is Aditya.
I just went through your project. I see that you are looking to make modifications in an exiting website such as change size of an image after it is uploaded, a page to choose homeroom teachers from a list, calculate GPA, search for male/female students, etc.
We can discuss more details about the project once you drop me a message.
Waiting for your positive feedback.
Best Regards,
Aditya
