I have a web-application which has been developed under codeigniter framework and php 5.6 [login to view URL] this application router os api is integrated and its running fine with php5.6 environment. Now i want this to be convert to php 7.2. The features I need to be done by an expert developer ; * It must have to work with php 7.2 flawlessly. * All the functionality of the application must have to be done by ajax(without page refreshing. * The scripts must be converted to work with latest codeigniter version. * At the end of the project this application have to be linked with my other relevant modules (Already written in php 7.2,) which I will provide at the end of the mikroTik api development process. And the developer need to edit the scripts to work with ajax. * Finally i will provide ioncube obfuscation with license key. The developer must have to able to obfuscate this application with ioncube. * I need an expert developer who understand mikroTik api, php 7.2, mysql, ajax and apache2. * Whoever read the full project phase please write down the current MikroTIk ROS version name along with your proposal.
