Use iPad as a Trackpad

I would like to use my ipad mini 3 as a good trackpad or touchpad for my computer, being able to use 1, 2, 3 and 4 fingers to be able to scroll through pages, switch applications and work areas and other functions, for less response time I do not care ir i have to connect the cable on the ipad and on the computer.

Does anyone know of a software that has this capability? all that I have used in this branch work a maximum of 2 fingers and always with a long delay.

If there is no software in this field would someone be willing to develop with me? I'm a C programmer, java, javascript, node js, react, python ... but without much experience on how to make interactions with the ipad screen to be passed via cable or bluetooth to the computer.
