We need an AWS Lambda function written in python that will do the following: 1. Read from an AWS SQS queue that receives JSON messages. Message Body: [{"endpoint": "[login to view URL]", "objectId": "s436dgsfe30edee9e454456f3da", "userId": "235223sdf2e235", "updatedAt": "2016-08-02T22:02:19+00:00", "action": "updated", "model": "summary", "type": "summary"}] These messages contain external API endpoints that must be called using parameters contained in the SQS message. 2. Calculates a HMAC-SHA1 signature from the message contents and 3 other variables, and validates the signature is correct by comparing it to the signature passed in the messages header attributes. 3a. If not valid, log an error to a DynamoDB table 3b. If valid, structure a URL from variables in the queue message and application level, and then make the external API call. GET [login to view URL] 4. Process the resulting JSON payload from the GET request and store the results in a DynamodB table. 5. If any error is received or occurs in the processing, store the error in a DynamoDB table.

Hi I am an AWS certified solutions architect based out of US with 13 years of experience - 5 of those working with AWS technologies The ask is fairly simple and I should be able to complete it within an Week's time. I will also provide step by step documentation with screenshots detailing how to deploy and configure the lambda function. If awarded I will reach out to you for further inputs on exactly what information needs to be logged based on your requirements. Also calculating a hash-mac is typically not a problem, but sometimes implementations call for some vendor specific information/ encoding/ headers to be passed - may need to discuss those with you also in further detail. I am very confident I can deliver a quality code complete with comments, documentation, test execution results in a timely manner. Past works done recently using lambda functions (at freelancer and other freelancing sites) a) Manipulate image files, upload changed files to S3 and send email b) CRUD operation with AuroraDB RDS c) CRUD operations with DynamoDB d) ElastiCache (Redis) Operations Thanks Dhiman California
