Who Am I
I am a software programmer/engineer. I graduated from graduate school of information engineering (M.S. in Information Engineering), had worked for several companies as a software developer and technical manager/director, and published seven books in the fields of database and system integration (3 PostgreSQL books and 3 MySQL books).
As a director of the Japan PostgreSQL Users Group (2010-2016), I organized the largest (non-commercial) technical seminar/lecture of PostgreSQL in Japan for more than six years, and also served as the program committee chair of the Japan PostgreSQL Conference in 2013 and as a member in 2008 and 2009.
Cuando era joven, vivió en Sudamérica por unos años. Recientemente, a veces vuelve a allí.
Now I live in Dublin, Ireland. However, I am considering to relocate to another country again because of financial reason and personal activity. The first reason is simple. Taxes and rent are higher than expected, becoming poorer than when living in Japan. The second reason is my personal PostgreSQL activity. In short, the company I am currenty working is a very bad environment to do open source activities. So, I have to look for a new company that welcomes my activity of PostgreSQL.
I love animals, music, science, math, astronomy, and physics. I play the piano and guitar.
