I came to know you through many positive feedbacks you received from employees.
I'm a system integrator living in Japan developing application mainly works using browsers.
I have a very unique application other freelancer made for me a couple of months ago.
But it does not have any admin or user controller and settings but it was only installed on CentOS.
I hope the app can be modified for many users to be able to create their own account.
I send you a detailed documents and URL for the app.
Please PM me if you have interest.
