Hi,
I've gone through your requirement and understood what you want.
We are having a team of highly experienced web and mobile developers and designers. We've done a lot of mobile applications till the date. However, as you have asked, I can't just share the project samples here as it is illegal out of the portal's norm.
Although you can have a view at our work samples from our website.
Let's connect to discuss the project in detail and to showcase our previous work too.
Looking forward to hearing back!!
