Dear Sir/Madam,
Hope you are doing well.
I have read your requirement and I can implement your system very comfortably within minimum timeframe.
I have developed many applications having similar kind of need. So, I am very well aware of about what kind of database it should follow and what process we need to follow to accomolish this kind of requirement.
Technically, I am expertise in Angularjs, Laravel, PHP, html/css, Android, Wordpress, Magento, Prestashop and Opencart. You can choose any technology as per your choice to build system. In web development, I have 5+ years of experience and created lots of websites, private applications, Android apps and many more related to eCommerce.
We can further discuss on your requirement to clearify each thing. Kindly contact me for your project.
Thanks
