Hi,
I'm the former CTO of a Finance company that provides cloud based mortgage processing solutions for some of Australia's biggest banks and lenders. I'm now out working on my own startup and doing ad- hoc development work like this to help pay the bills. Here is a link to my LinkedIn profile - [login to view URL]
I've read your project description and I would like to offer my services to make the change to your app. I aim to develop lasting relationships with my customers.
I've got a lot of experience with almost all aspects of Android application development. I produce a very high quality level of work and can ensure your application looks and works beautifully. I have worked a lot with the latest Android Material Design specifications. I'd be happy to share with you some screenshots of other applications I have developed.
I'm available to start work immediately and can communicate with you however you like (Freelancer, Skype, Hangouts, email).
I look forward to hearing from you.
Regards,
Brad
