I want some suggesions

Sir,

I'm studying computer science engineering course as a degree and i now entered into last semester of my course so i had a mini project and a major project to be done so I'm looking for the ideas which must be new unique but realized that it's not possible so I'm hoping that anyone of this community will help me by giving the ideas to implement as a mini and major project (both differ in their structure of course ) so please give me some suggestions for my development

Thanking you sir,
