New Operating system

Job ID: 31722055

Budget: $50,000 – $0 USD

Hi. I am looking for a systems programmer that can develop a fully functional new operating system for the raspberry Pi chip (64 bit).

This operating system has to be well structured for (primarily) touch screen functionality and also for mouse and keyboard usage like the general pc.

I want a new none existing operating system that will allow me to connect my raspberry Pi chip to a touch screen display and run smoothly with everything, but especially with business orientated software such as typing on word processors and spreadsheets.
It must also be able to open file formats of a wide range (as flexible as Windows)
