Dear client!
I read your job post and I am very interested in it. I developed many Android apps and they are living in Google Play Store. I am good at implementing REST api, parsing JSON, 3rd party libraries. I have also rich experience in team work with Jira, Trello, Slack, Skype and Github, Bitbucket. I like OOP and MVP so that you will receive robust and clean code. Please discuss in more detail. Looking forward to hearing from you. Thanks.
