Summary
🤩
RockstarYancey Wang is a Principal Software Engineer with 12 years of experience specializing in networking and large-scale systems, proficient in Go, C++ and Python. He builds high-performance L3/L4 tunneling and cloud VPN mesh solutions—work that contributed to Airgap's acquisition and his rapid progression to Principal at Zscaler. Author of widely used open-source tools such as udp2raw, UDPspeeder and tinyfecVPN (15k+ GitHub stars), his projects focus on forward error correction and robustness over lossy, high-latency links. He holds top-ranked engineering degrees (MEng USTC, MSc Clemson 4.0) and maintains an academic publication record, blending research rigor with production-grade networking engineering. Based in Clemson, SC but actively open to opportunities in the EU, he brings deep low-level networking expertise and a track record of shipping resilient, performance-critical systems.

Oct 2017 - Dec 2021
A VPN Designed for Lossy Links, with Build-in Forward Error Correction(FEC) Support. Improves your Network Quality on a High-latency Lossy Link.
Role in this project:
Back-end Developer
Back-end DeveloperContributions:10 releases, 261 commits, 256 pushes in 4 years 2 months
Contributions summary:Yancey contributed significantly to the `tinyfecvpn` project, which focuses on VPN technology with Forward Error Correction (FEC) for lossy links. The user primarily implemented core functionality related to the VPN and FEC, including the creation of the `tun_dev.cpp` and `tun_dev.h` files for handling the TUN/TAP interface, implementing keep-alive mechanisms, and integrating MSS fixing for TCP connections. Furthermore, the user added functionality for handling truncated data. The commits demonstrate a focus on the core networking and FEC aspects of the VPN.

Nov 2017 - Aug 2020
A Lightweight Port Mapping/Forwarding Utility using epoll/libev, supports IPv4 and IPv6 for both TCP and UDP
Role in this project:Back-end Developer
Back-end DeveloperContributions:7 releases, 109 commits, 76 pushes in 2 years 10 months
Contributions summary:Yancey primarily focused on developing and refining the core functionalities of a port mapping/forwarding utility. Their contributions began with the initial setup and initialization of the project, encompassing the foundational C++ code. They further implemented the core networking logic to handle TCP and UDP, adding support for IPv4 and IPv6. These changes included integrating libev for event handling and establishing a working UDP implementation.
