Daisuke Masuda (born January 1982), also known as x5gtrn, SAEKIKAZUMI, or DJ Ekusi, is a freelance Japanese software developer who aspires to gain recognition as a DJ. I balance programming and DJing as my lifelong pursuits and am a devoted enthusiast of both music and literature.
I am a passionate admirer of Richie Hawtin, Sven Väth, Ryuichi Sakamoto, Ryu Murakami, Kenji Eno, and THA BLUE HERB. I draw inspiration from their creativity and vision.
