Hello,
My name is Deniz, I am a senior web developer. It seems you want an API app for restaurant orders and I've built similar web applications before. I can do it within 24 hours. Also, I've work with 4-KMY before. I can show a reference to you.
I have 10+ years of experience with PHP, CSS/HTML, JavaScript and MySQL. Please send me a message to discuss the details.
Thank you.
