uninstalled play services&google app - system unstable
The phone might still be using the old caches of your old Apps that you have already uninstalled.

So, I suggest you to Go to recovery and try to clean cache and dalvik cache.
Then try to reboot (which may take some more time than usual because you have cleaned all cache) and see it should boot properly.

If this do not help you then you have to go for factory reset as suggested by Firelord.
