Hello,
I'm an iOS app developer and a member of a small team consisting of highly experienced iOS, Android and backend developers. Our team have UI/UX and graphics designing skills too. We develop native mobile apps using latest technologies. We have consistently delivered high quality projects within specified time and budget, which has earned us many positive ratings, as you'll see in my profile.
I have gone through the project description and I believe that our skillset would be ideal for your project, however, I'll need a little more detail to give more accurate estimate of time and budget.
I have few questions regarding the project:
1. Would you provide the UI/UX and graphics required for this or you want them to developed as part of the project?
2. Do you have any existing design documents, algorithms, source code, etc. that you would want to provide us for the project?
3. Do you have any specific preference of the technology, libraries, etc. for the development of the project?
4. Which all platforms/devices do you want to have support for?
I would be happy to set up a convenient time to discuss the application you're moving and some ideas about the safest way to get it into the cloud.
Regards,
Sam
