Dear Customer,
I have 7+ years of software testing experience. Others are saying that I have a magic right hand, because usually 5 minutes is enough for me to face into the first serious bug.
During my career I was always the tester who found 3 times more issues then the others. I have like a hawk eye when it comes to bug hunting.
I'm professional, well organized, my bug reports are always clear with well defined steps to be able to reduce to zero the overhead caused by asking questions back and forth because the report is not clear.
I'm using every week minimum once such a POS terminal, so I have real life experience with them.
I have also see the cases when they have trouble to accepting the payment/input(s) of the user so I know the special test cases for checking your software.
I'm counting with the given milestones, because my experience has shown that in the first beta release many bugs will occur. By fixing those bugs, you can break other part(s) of your software that you are not aware of. So after fixing the bugs it would make sense to execute again a full test run.
Any additional test run costs $1200. (Freelancer.com did not allow me to fill the form that way)
You get the results of each test run within 2 days.
Best regards,
David Gangel
