Hi, Chris.
I have gone through the brief and I can see that you want to make a PHP script that receives data from Unbounce and reformat it into an XML feed and it can be sent to your client CRM.
I specialize in full-scale web design & development including PHP | Laravel, React.js, Vue.js, Angular, JQuery, JavaScript, Bootstrap, MySQL, MongoDB, Node.js, Payment integration, AWS amplify.
Please check my outstanding works.
