Laravel Application for Online Expert Consultation (archived)

He asked for payment outside of freelancer.com on paypal or upwork. When the request was rejected, he cancelled the project. He wants to focus on project outside freelancer.com. So much of our time got wasted. We are very disappointed. He should not have taken the project on freelancer if he wants payment outside of this platform.

PHP Zend, bug fixes and upgrading from version 2 to 3

We will work together for more projects as well.
