A database enthusiast who has been working on database backend and query optimization.

In the past 4+ years, I worked at TigerGraph as a software engineer and as a software engineering manager. I majorly contributed to GSQL, the query language of TigerGraph, and the query processing engine in terms of query execution, data ingestion, and cross-region replication.

Before joining TigerGraph, I earned a Master's degree in Electrical Engineering and Computer Science with a research interest in database systems, query optimization techniques more specifically, at University of California, Merced.

Prior to the advanced degree program, I worked for 3 years as a software engineer in South Korea and developed a variety of web applications for public organizations, academics, and enterprises.
