As well as 4 years technical experience with iOS and Android, I also have experience building custom apps for mine long term clients.
For a previous client I built a database mapping and admin management tool for their new network for doctors, which was based on Amazon AWS using S3 as a storage for images and EC2 for admin and database handling which follows the principles of an basic functionality of a highly compatible, fast and scalable. This was used as the foundations for the whole project.
I am NOT going to recommend that you use something similar. We built the custom code for reasons that made sense at the time and I have come to believe that it may have been better to use an out of the box solution.
However, the project has given me an excellent understanding of the principals involved in building and managing a AWS and mobile apps and the technical advantages and disadvantages of choosing one. I believe I would be in a good position to analyze your requirements and advice on the best manner of proceeding.
In our app portfolio we have all categories app like Business, Entertainment, Utility, Lifestyle etc.
We are having our own dedicated app development team which includes Mad designer, Geek coders, Smart QA and above all, a hunter delivery cum project manager.
