AWS Backend Experts Needed - Python

Need to implement this project [login to view URL] Need to follow the same solution and then we need to give an option to download only srt or only converted audio or both. Also the solution should have batch processing, job queuing and so on implemented. 1. User Sign Up/Login authentication mechanism, Payment Gateway Integration should be implemented. 2. Input option to get the file and we need to set the length limit for the entire operation. Provide a S3 downloadable link after the job is complete, also need to delete it after a suitable time period (say 24 hours). 3. No need of video file or srt to be stored in DB. (Amazon DocumentDB for storing user profile related data (password, username, other details if needed)). 4. Should have a solution to batch process ? and how to rerun a job if its stopped midway or halted ? (run the process every thirty minutes to complete the transcribe, translate and synthesize process; so all uploads will be temporarily stored in local SSD and we can keep a record in DocumentDB on which jobs are still not completed) -- A strong mechanism to handle the failures should be implemented. For frontend suggest few themes [login to view URL] and I shall buy it, so that you can integrate. Budget - Not More than 15K INR
