Hello, I am a UK-based Android professional and I would like to work with you on this project.
First, here's more information about me: I've been an Android developer since 2011, originally creating an app for an upcoming telecoms company. Since then, I've gone on to deliver excellent value and first-class service to clients all over the world, with some of my more recent work being done for the Australian Department of Agriculture, Fisheries & Forestry. In short, I believe I have the professional background that you require. I pride myself on my excellent service and development skills.
So, back to your project. I'm willing to work with you to establish exactly what needs to be done and write that up, so that we both can agree on the work that needs to be carried out for everyone to be happy. I would then develop your app, from start to finish, while paying extra attention to the areas you have specified: the Material design theme and the overall user friendly nature of the app. Naturally, I would be submitting evidence of the work performed and requesting feedback where needed.
In your reply to this message, please could you send me a link to your existing Android app on the Play Store, just so I can get more of a feel for what you're looking for from this project? If you'd also like to go into more detail in general about what you're expecting, that would be fantastic.
Thank you for reading, I hope we can work together on this project.
Kind Regards,
Michael Stubbs
