I'm pursuing a master's degree at Waseda University's Graduate School of Information, Production and Systems, following my studies in Software Engineering at Xiamen University.

My work spans Linux systems, backend engineering, and applied AI, with a focus on building reliable software and evaluating it through meaningful testing and reproducible experiments. I'm also developing my foundation in digital hardware design and verification as I explore hardware-oriented research.

I play the piano, enjoy badminton, and occasionally lose track of time editing music videos. I'm fond of Haruki Murakami's novels and the films of Christopher Nolan and Quentin Tarantino.
