Hi
I can understand your project requirements that you need a login system built in ZF2 with Doctrine2 and along with hybrid, so user can login with password or social media.
I am especially expert in ZF2, i am well aware about its module structure, factories, dependency injection, configuration by arrays, routes and event driven development approach.
To work on your project i will clone skeleton project and by help of composer will enable doctrine modules in ZF2.
You would need a user entity and table would be generated from that entity. By Zend/Auth library login functionality will be performed and social media would be integrated.
I am available to start work on your project and will give you work within given time.
