He has contributed to big data related open source projects such as Apache Sqoop and Apache Flink for 3 years. He is a committer of Apache Flink since June 2015.

I would like to thank my girlfriend, Sunmi Yoon, and my lovely dog Reo for standing by me. I would like to thank The Flink community for their great contributions. Apache Flink couldn’t be improved without their valuable contributions.
