Hi,
I am a new freelancer. However, I am fairly experienced in programming. As I used to run online business mainly digital services. I am specialized in automation.
However, I am very well experienced in the project you have mentioned. I have created API for whatsapp messaging for small organizations. I find this project to be very similar. I am a discord user as well. I have deep knowledge in Discord bots, servers etc.
Please contact me on skype : manu_shamil or try direct messaging me on freelancer chat. We will try and sort this out.
Looking forward to work with you
