Occupation: software engineer
I am a freelance 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.
I love animals, music, science, math, and physics. I play the piano and guitar.
