I was able to significantly improve the loading time of the project's main page, reducing it by seven times. Additionally, I made changes to the data structure which resulted in lower memory and CPU usage, saving the company money. To further optimize, I configured the MySQL database to fit the company's specific needs, resulting in lower CPU usage for query processing and ultimately cost savings.
I am a skilled engineer with a Master's Degree in Computer Science and over 8 years of experience in backend development, as well as 5 years of experience as a full stack developer. I have worked in both FinTech and HealthTech industries.

My main duties involve designing and improving systems, as well as ensuring that the codebase is thoroughly tested through unit and functional tests, or implementing via Test Driven Development (TDD). I have extensive experience dealing with large legacy codebases, including covering them with tests, refactoring, and optimizing them.
