DNS Scanner in NodeJS for AWS Lambda

We are looking for someone who understands AWS S3 and AWS Lambda, to migrate an existing solution written in Bash to NodeJS. The code in Bash can be provided for review/migration. Desired end result is a function in Lambda (that runs based on cron) that can use the command 'dig' to run DNS queries and retrieve/upload files to an S3 bucket depending on the output of the main application. The original Bash script heavily relies on awk and grep, with minimal regex.
