Rockstar🎓
Top SchoolWei Tan is a Staff Software Engineer based in Shanghai with 13 years of deep systems and virtualization experience, currently focusing on vehicle virtualization at NIO. He has a strong background at Intel and ZTE working on ACRN, device emulation, kernel-level debugging, RT Linux tuning, and packaging full Android systems into containers. An OS enthusiast and prolific open-source contributor, Wei has made impactful low-level contributions to notable projects like the ACRN hypervisor, Zig, Elvish, Zellij and The Platinum Searcher—often improving concurrency, stability and hardware integration. He combines pragmatic performance tuning with hands-on kernel and driver work, and has a track record of turning complex hardware virtualization challenges into reliable platform features. A detail-minded engineer, he often surfaces subtle correctness fixes (e.g., BPF/BTF metadata and I/O vector bugs) that prevent obscure runtime failures.

Dec 2014 - May 2017
A code search tool similar to ack and the_silver_searcher(ag). It supports multi platforms and multi encodings.
Role in this project:Back-end Developer
Back-end DeveloperContributions:8 commits, 4 PRs, 6 comments in 2 years 4 months
Contributions summary:Wei primarily focused on improving the performance and functionality of the code search tool. They refactored the file searching mechanism to use goroutines for concurrent execution, and fixed file path bugs. Additionally, the user implemented a feature to allow the `-g` option to behave like `ag` and added a new optional multi-finder feature. They also added benchmark tests to assess the code's performance.
