Hi!
My name is Pavel, I can develop you this CRM project.
Based on your task I may suggest to develop a web app for your project. You will have SEO opportunities enabled and cover users of mobile devices and also those who prefer to open web application.
The web app will be 100% original in Java or PHP, with MySQL database and will feature custom CMS, no WordPress, no stolen or third-party scripts.
Frontend will be made with Bootstrap4/MDBootstrap/JavaScript/AJAX, this is the cutting-edge UI technology. The site will be fully responsive and look well on all screens, including mobiles.
I will also help you to install and setup everything, ongoing support for your project is also possible. For the hosting, I would recommend Amazon AWS, I know their systems deeply and even have a grant from them. But this is not mandatory, you may supply any hosting of your choice. I may also provide you consulting on the best web development practices.
If you are interested, please let me know and I will send you full feature list for the system and write you detailed technical plan.
Generally, I build many projects as an independent developer, they are all custom coded with original features and twists. I have also won the grand prize in the Freelancer.com Developers Contest.
Can start the works instantly, just drop me a line. Thank you!
