AWS-SDK NodeJS - Build a function that streams files between S3 buckets

Hi! I need someone to write a function, that will perform an S3-specific task on a NodeJS Lambda. The function needs to: - Async stream an S3 File Download into the function. - Async stream an S3 File Upload out of the function. - Provide ability to insert middleware, to transform the stream. - Does not write anything to disk. The method should look like: export async function MoveFileBetweenBuckets(previousBucket, previousKey, nextBucket, nextKey, middleWare = null) { Step 1: Get S3 Stream Step 2. Process Stream if middleWare (middleWare is an async JS function, which takes inputStream and returns an outputStream) Step 3. Upload S3 Stream } Please do not apply for this project if you don't have experience with AWS Javascript SDK in Streaming Scenarios. This function will be deployed on a time-and-memory-limited lambda and handle large (up to 20GB) files, so everything must be streamed without hitting the disk in order to make this operation fast.
