I'm a developer at NAVER Korean IT Corporation. I used to be a project manager of CUBRID open source database. Now dedicate my full time to Node.js development. At NAVER I develop a real-time distributed log search system which uses ElasticSearch, Kafka, Storm, CUBRID, Redis, and Node.js. I also maintain Pulsr, a fast Node.js Web Framework, in my personal time. See my Github for other modules I have created.
