Javascript and AWS expert

I need an expert Javascript developer who can build a tool to capture field level analytics for forms. This would be Google analytics for forms. Something inline with [login to view URL] We need a way so that the site owner can: a) Register on the application b) Add a javascript tracking file on his website OR through Google tag manager c) The tool starts capturing the analytics for the forms added on their web page Let’s take an example, on a website, there is a contact form with the following fields: Name Email Phone Number Message Submit button So, the form analytics tool would capture the following: How much time user has spent on Name field? How much time user has spent on Email field? How much time user has spent on Phone Number field? How much time user has spent on Message field? How much time user has spent on Submit button field? How many users fill Name field BUT does not fill Email field? This is called as drop off. How many users fill Email field BUT does not fill Phone Number field? This is called as drop off. How many users fill Phone Number field BUT does not fill Message field? This is called as drop off. How many users fill Message field BUT does not click Submit button? This is called as drop off. How many views are there for the form? How many conversions for the form? How much time it took to fill the entire form on average? ================== I need to deploy this on AWS. I am thinking of using AWS SQS and AWS Lambda. The javascript code needs to be easily added through Google tag manager, so need integration in the system.
