Hey there,
I understand that you're looking to create API to buy & share Amazon coupons for your team members. You want the APIs to be highly secure. Also, I have gone through your other requirements and I am confident to mention that I can work on this project and make it a success for you.
I have excellent work history, top ratings & feedback from my clients, so I assure you that you're in the right hands. If you have any questions or concerns, please let me know at earliest.
Best Regards,
Wasif
