As in, completely by yourself from scratch? You'll have to read and implement the actual specification, which is in an ISO patent you can find over there: https://www.qrcode.com/en/about/standards.html

That would be an enormous, complex project though, I highly recommend using an existing library like ZXing (as this project does too).
