About

I'm a software engineer passionate about building nice experiences for both customers and co-workers.

I excel at writing clean, readable, maintainable, and testable code, while building reliable, scalable, and efficient architectures.

My background in mechanical engineering gives me a unique perspective on system design and problem-solving.

I'm a quick learner, and I'm always open to new ideas and technologies. I thrive in collaborative environments and enjoy mentoring others.

I'm originally from Mainland China, and now living in Japan for more than a decade.

I'm fluent in Chinese(Mandarin) and Japanese, and can communicate effectively in English.
