The files will be remotely access and write files to Amazon S3 2- The script will need to process LARGE text files in a fast optimized manner. 3- After the project has been awarded the candidate needs to be available in Skype to initially discuss the project. 4- The function and its setting needs to editable programmatically (example: number of concurrent processes, maximum execution time etc...) 5- Provider must be available for support 90 Days after delivery of the product. Please ASK questions before bidding. Amazon Web Services Experience a must!
