PostgreSQL Person of the Week Interview with Takayuki Tsunakawa: I’m a Japanese man who was born and lives in Japan, near Tokyo. I am visually impaired by nature, and I have only enough eyesight to feel the light now. But I had somewhat better vision when I was a child, and enjoyed playing video games with friends or alone. I can’t see the screen, so I use screen reader software that reads characters by synthesized voice.
