How often have you faced code optimization tasks?

Code optimization is an important part of work, especially at the senior level. In my experience, optimization tasks arose regularly when:

• It was necessary to improve the performance of bottlenecks (for example, reduce response time or decrease load on the database).
• It was needed to reduce memory or resource consumption.
• It was important to simplify and make complex code more readable and maintainable.

Examples of optimizations included refactoring loops, using caching, optimizing database queries, as well as applying more efficient algorithms and data structures. Optimization is a balance between readability, maintainability, and performance, so it is important to approach it consciously and measure the results.
