I'm an Audio DSP Algorithm Engineer based in Shanghai, China, born in 1989. Audio effects and spatial audio are the areas I know best and enjoy working on the most. I spend part of my time on research and the rest on engineering — audio algorithm optimization, development on embedded systems, and audio DSP architectures in particular. My usual tools are C, C++, Rust, and Python, and I do most of my work in Neovim and recently the Pi Agent.
