Hey there,
How are you doing? Alright, so I get the picture that you're looking for a PHP developer (symfony framework) in order to fix the backend issue of an app. Well, I am pleased to let you know that I have expertise over PHP and can help you with this project.
Can you be kind enough to share project details with me? So I can better provide you with time frame & pricing details. If you have any questions or concerns, please let me know. I am looking forward to your positive response.
Sincerely,
Talha
