I can setup apache to proxy pass the requests and response from SSL (port 443) to the relative paths of your front-end and back-end. Please be aware that I would require access to your server to do this.
I have been a website developer for more than 6 years, previously working for a private company making administrative website and developer tools. I work with websites built with PHP, MySQL, Javascript, Wordpress, Laravel and more.
Please feel free to send me a message so we can discuss further details. Thanks.
