Was there any task that you particularly highlight as a technical challenge during your work?

One of the technical challenges was optimizing the performance of a distributed Java application with a large number of parallel requests. The goal was to reduce response time and database load.

The solution included:

• Analyzing bottlenecks using profilers and logging
• Implementing application-level caching
• Optimizing database queries and indexes
• Using a thread pool to control parallelism
• Redesigning some components for asynchronous processing

This experience demonstrated the importance of a systematic approach and a deep understanding of JVM and database operations for solving complex problems.
