Our processing consists of several steps where ETL is implemented in Java using Spark as the main tool. Every step provides a dataset stored on S3 as parquet files with custom batching logic implemented. The result of the workflow is custom aggregations used later for API calls to support the reports generated on front-end application. In between the main logical steps there are several additional steps to update the cloud storages such as Athena or provide the data to the additional endpoints. The workflow scheduling and monitoring is handled via Airflow. Given the information above, the tasks to work with are related mostly to adjusting the Java ETL code, Tech dept improvements including performance optimization, data inconsistency investigation (in comparison with the legacy system as well). Scrum is used as a development methodology. Tickets/tasks are not assigned strictly, it is always possible to pick anyone interesting to you from the backlog.
