Our client is the UK based largest marketing company responsible for organizing events for all of their clients, These events and campaigns run for days or months. At the end of each month, they need to apply Taxes for all the events held and there are so many rules depending on each client, event types and durations.
These report files are being generated from their Admin panel and saved in AWS S3. We created Lambda functions to execute Python scripts that make all these Tax applications automated depending on a lot of rules. And after applying these rules saves these files again in s3 bucket with proper folder structure.
