About Me

Hi! I’m an undergraduate student at Zhejiang University majoring Information Engineering and expected to gain my bachelor's in March 2025.

I spent most of my time coding as intern, RA or in open source community:

I’ve got many internships and tons of projects with a variety of tech stacks. Check my github page to find out more.
I’ve been visiting SUTD working as research assistant in team of Prof. Shuhao Zhang, where I implemented a performant TSPE db4nfv.
I’ve been contributing to bpftime which brings ebpf to user space.

I’m a vimer, rustacean, gopher, interested in anything geeky. I’m interested in designing and implementing complex systems, especially in cloud computing, networks and linux kernel. I never stop exploring new fields and topics, please check out the recent posts at the bottom of this page.
