Hello,
my name is Dheeraj and I am an experienced PHP, Codeigniter, Wordpress, AngularJs, Node.js, Mobile Applications user with over 7 years of experience. I understand you need to allow a user to login using multiple browsers but block them from sending the same request at the same time to prevent doubling in data.
I believe I am the perfect fit for this job because of my extensive knowledge in website applications like PHP, Codeigniter, AWS setup as well as Payment Gateways like Authorize.net. This makes me an ideal candidate for preventing same post action from multiple browsers at the same time. With my expertise in different types of website like Blogs, E-Commerce Websites, Forums and Social networking I can provide strong and best work as per your requirements..
Please come over chat and discuss your requirement in a detailed way and ready to start this task from now onwards.
Thanks & Regards
Dheeraj Sharma
