Kohei Kawasaki
App Creator / Software Engineer
I build independent apps driven by a simple goal: "Make life richer and more convenient." I believe apps should be more than just tools—they should be experiences where design and functionality harmonize to spark joy in everyday use. Starting with 'Listening Mania,' a listening practice app designed to break language barriers, I am dedicated to creating products that solve daily challenges and open up new possibilities.
