Plugin Development

I am student of Coumpter Science and choose oxwall pulgin development as final year project. Our team has 4 members and we have grip on PHP, MySql to some extent.
we had coverd some advance topics of PHP and still working on PHP.
We had read Plugin crash course but have some confusion in mind.
Thats why we want complete documentation that have all classes with their funtions and syntax so we can build advance plugin easily.
Is there any core developer available that can guide us time to time when we need it. If their is any developer available so please tell us.
Thanks in advance
