Hello there! My name is MST. SURAEA, and I am here to offer my expertise as a freelancer in creating an Amazon Fire TV App that does the following:
1) Disables the Fire TV Sleep Timer so the app can run 24/7 without turning off.
2) Opens a web page that I'll provide (the url).
I understand from your description that you need a simple app created that does these two things - opening a web page and disabling the Fire TV Sleep Timer. I have extensive experience in ecommerce, eBay, Amazon, dropshipping, Shopify, Wordpress, Facebook marketing and more.
I guarantee good workmanship as well as responsibility, reliability and honesty. You won't be disappointed with my output! Please let me know if you'd like me to discuss further or answer any other questions?
