Hello.
I understand that you would like to re-work your app which was previously built on AppMachine. I also understand that the re-work would involve, among other things, updating/changing its 6 blocks.
I have a team of very experienced PHP and Javascript programmers who are also well-versed in Mobile App Development, website design, and the Google App Engine.
We are all ready to deploy our expertise to make your App function optimally with the features you have highlighted, including loyalty points, QR codes, blog and contact features.
