Hi, I'm a young UK developer with over 10 years of experience in working and creating websites, specifically with backend systems.
I have skills and the ability to create a multitude of backend systems, including:
[X] Login/Register/Forgot Password
[X] Clients/Portal Areas
[X] Support Ticket Systems
[X] Forms
[X] Payment Integration
And pretty much most things related to this topic, all of which would utilise HTML, PHP, CSS, JS, Jquery, SQL.
I would need more information to help give you a better or more suitable price and timeframe; additionally, you would get myself and my business partner's full attention; the more the merrier for a project like this.
If you're interested, I look forward to your messages! Thanks.
