What impact did you have on previous projects?

In previous projects, I significantly improved the performance of services in Go by optimizing algorithms and reducing memory allocations. For example, I rewrote a critical data processing module, which allowed reducing API response time by 30%. I also implemented a monitoring and logging system, which helped to quickly identify and fix errors in production. Additionally, I participated in code refactoring to improve readability and maintainability, which accelerated onboarding of new developers.
