Hi, hope you are fine. I have gone through your job description. You are looking for someone expert in node.js, mongo DB and AWS so that he can integrate and deploy your solution on AWS.
I'm AWS Certified Technical Professional with more than 5 years of experience working with node.js, mongo DB and deploying web applications on Amazon EC2 and Beanstalk.

Looking forward to know more details. Thanks
