Dashboards PCM

I am looking for someone to develop a comprehensive dashboard platform using visualization to schedule/programme data. I have existing data that will be used and the dashboard will be uniquely tailored to specific roles or groups of users. The platform should have the capability to store, sort, and display multiple datasets in an intuitive and aesthetically pleasing way. It should also be fully integrated with our existing system. The exact requirements and specifications are yet to be determined. We need somebody with previous experience in dashboard development who can accurately meet all of our requirements.
