Good morning, Greeting of the Day!!
I understand that you're trying to find a "APP DEVELOPER" who can create "SOFTWARE" to send WhatsApp buttons without using an API.
I've worked on a lot of projects over the past seven years, and I'm sure we can complete your job with excellent results. And maintain the abilities:
PHP, software development, web applications, and other technologies
If you want to talk about how we can help you with this project in more detail. You are welcome to get in touch with me directly or ask any other questions you may have. I forward hearing from you soon!
Regards and thanks
Fatima
