Hi there, I do have expertise in Software Development & Software Architecture. I'm a Software Engineer by profession. Your project, Appointment maker software, its kind of an interesting thing for me. I would love to develop architecture for this and further deploy my team for its accomplishment. What I require is some detail of the project which you have in your mind, so that I can advise you as well and after modifications in your idea (if there be any), we can carry this out.
With Regards, Waqas
