Hello dear. I hope you are fine.
I've read your job description and it's very interesting to me.
As an experienced full stack developer I can help you perfectly.
I have rich experience in PHP, CodeIgniter, RestAPI, AJAX, web design, JS, Jquery and so on,
It'd be really appreciated if I have a chance to show you how could I contribute to your project to meet your goals.
Looking forward to hearing from you.
Thank you.
