Correct AJAX queries and build php scripts

I have a php system that need few changes. First I have a program that is ajax based and you move up and down the sessions and the database it should be updated with the order. currently if you do one change every 1 minute it is updated but if you do 5 or 6 moves then forget it. Second task has to do with qrcode storing. The scanning has been already implemented. I have a video showing the problems that will provided to the people I will consider for this job. If you are not experience php and ajax developer dont waste your time as I am not looking for someone to play with the system but someone to fix it in max 4 hours.
