Name Trivia

My family name MUSHA (武者) means samurai, or to translate it literally, "brave one". My given name, Akinori (晶紀) was named by my parents after two kanji that appear in a phrase "shine in the next (21st) century".

Since I first learned to code at the age of around ten, I have grown my programming skills to the level I can write apps I want, contribute to OSS, and develop software products and services that make our lives happier. I still enjoy writing code to make the world a better place.

Now I have my own kids; I named them after the family story in the hope that they will pioneer the new century and weave the good intents into the society and history even after I get dim.
