Hi
I read your project description. I am very interested in your project.
So I think that I can build your app wonderfully. I have 8 years experience of native android and iOS developing and I have 4 years experience of Hybrid app developing.
I often developed Backend(including admin panel) with mobile apps. In backend developing, I used PHP, Java, Spring, Hibernate+JPA, Nodejs and I used Postgresql, Oracle, Mysql, MongDB as database. I would like to use angular js in order to build admin panel.
I hope to work with you.
