Dear emeraldbc,
I have worked on countless projects in PHP that interacts with MySQL, so much that I have written my own class to simplify the process. I've done account registrations, account managements, dynamic update to pages, and much more.
I also have lots of experiences with JavaScript and AJAX, accomplishing real-time updates on the page without refreshing it. If you want to see some examples, they are available in my portfolio.
I look forward to hearing from you. Thank you for your time.
Sincerely,
Kylorcache
