Can you tell about the results achieved in your last completed task?

In the last task completed, it was possible to implement parallel execution of multiple network requests using ExecutorService, which significantly reduced the overall response waiting time. All responses were successfully combined into a single list, simplifying further data processing.

Additionally, database query optimization was performed, including adding indexes on key fields, which increased data retrieval speed and reduced server load.

As a result, the application's performance improved and stability increased under high load.
