Amazon Flex Block Selection Platform

I need a reliable developer to create a platform that can select blocks for Amazon Flex as well as other delivery services. The successful execution of this project largely depends on your previous experience on similar projects, so please include details of your past work relevant to this in your application. The key functionality of this system should enable real-time block detection. Thus, your background in developing real-time systems will be greatly advantageous. Your understanding of the Amazon Flex and other delivery platforms will be crucial. Looking forward to your proposals, impress me with your competency in the development of this type of system.
