Can you tell about the most challenging technical or project-related challenge you faced at your previous job?

In one of the projects, the most challenging technical issue was ensuring the system's scalability during a sudden increase in load. For example, a Python application handled a large number of requests, leading to performance issues and memory leaks.

To address this, we:

• Optimized critical code sections using profiling.
• Implemented asynchronous processing with asyncio to increase parallelism.
• Switched to using connection pools with the database.
• Set up monitoring and alerting for quick response to problems.

This experience taught me the importance of a systematic approach to problem-solving and continuous architecture improvement.
