Gym login dates and times

I am looking for a talented developer to create a tracking system for my gym that will track members' login times and dates. Specifically, I require this system to have the capability to export data into a PDF format, and a real-time update feature would be desirable. This system will be used to monitor the attendance of members in my gym. It would be useful to have data exported from the system for further performance analysis. I'm looking for someone who is experienced and can quickly develop the tracking system that meets the above requirements. Thank you for your interest and I look forward to seeing your proposals.
