This is the start of my engineering experience. I also have been developing an open-source software, the name of which is Jiemamy ( http://jiemamy.org ). Additionally I often attend to engineering study sessions and sometimes deliver lectures. And I wrote technical articles to contribute to magazines, Nikkei-Software and so on.I love Java and its ecosystem. I am not only a user of opensource softwares, but also a developer of opensource softwares. I love to collaborate with hackers to develop valuable products. It's because these experiences are attractive for me, I switched my job as a software developer in 2008. Now I have worked as an R&D staff for a system integration company in Japan to produce our own web service.My recent target to focus on is machine learning, such as recommendation, clustering, classifying etc. The total amount of the information on the Internet is increasing. However, what someone will be interested in is only a handful of these. A most portion of these is harmful rather than for naught.
