CRM App

A CRM platform that allows the company's sales department to have all the information related to their clients in one place by creating a client profile where all the documents can be uploaded and reviewed by staff. The platform's intuitive comment system always provides up-to-date feedback.

I delivered this project using PHP, JavaScript, jQuery, and MySQL on a tight schedule of two months. I also provided all the maintenance and updates as needed. With this project, I contributed to the following:
• Exponentially increased productivity due to access to all customer information in just one platform instead of using less productive or insecure methods.
• Improved client retainability and overall satisfaction by 11% in just one year of usage due to quicker feedbacks from other departments without any loss of information.
