Hello,
As per requirements, I am proposing to build custom designed task tracker website in php which will have multiple users authentication and login facility so users will login through their id and password to get access of the website and then can see the task, modules assigned to them only like upper management can assign task, see every associate details and progress everything but the lower resources or team leaders or workers can only manage their roles and take actions against their specified roles.
Details are pretty clear to us as you detailed the steps. Now let's discuss execution approach in private message thread and then we will proceed from there if you will find us suitable for the work perhaps I am sure you will find us best to go ahead..
Waiting for your response!!
Regards,
Vancha
