I'm Hyeil Jeong, a tenacious backend developer.

My goal is to become a developer who has a good influence on people, thus I always struggle with how to achieve my goal.

• I never leave broken windows unattended. I always struggle to improve performance and code quality.
• I use rigorous proof to make the best decision for the situation. I believe that the best choice can be made only by proving the tradeoff of all cases with tight logic and experimentation.

• Clean code & Architecture
• Refactoring
