Hyo-jeong Lee. Seoul, Korea

I graduated from Seoul National University in Korea with a master’s degree in computer science and majored in scalable techniques on system. Currently, I am working for SK Telecom.

I am interested in followings:

• Parallel Computing
• Troubleshooting with multi-thread concurrency
• Linux/Unix environment
• System performance tuning
• Automation in the development process
• Computer Science Education

In detail,

• Parallel Garbage Collection policy of Java Virtual Machine (JVM).
• Memory management of Operating System (e.g., Linux Kernel).
• GPU memory management on virtualized environment (e.g., Docker container).
• Scalable logging technique on Database system.
• Distributed File System (e.g., HDFS, Lustre) and data management middleware.
