About Me


Hi, my name is Edward J. Yoon (윤진석), was born in December 21, 1979. I’m interested in linear algebra, machine learning, graph theory, and distributed systems.  I’m also an open source software developer. I’m currently developing distributed system clone projects such as Apache Hama, MRQL, BigTop, and Horn on the Apache Software Foundation.
