Summary
🤩
RockstarShiwei Chen is a software engineer with nine years of experience specializing in backend and infrastructure engineering, currently based in San Jose. He holds an MS in Computer Science from Georgia Tech with a machine learning focus and a BA in Applied Mathematics from UC Berkeley, pairing strong theoretical foundations with practical systems work. Shiwei has driven measurable performance gains in production—e.g., cutting plugin load times by over 90% at TikTok—and has deep C/C++ expertise reflected in substantive contributions to popular open-source projects like libcpr and a user-friendly C/C++ networking library. His work often targets core library robustness and performance, from replacing std::async with a custom thread pool to optimizing memory and I/O subsystems. Comfortable across distributed systems, CI/CD, and backend APIs, he also brings a knack for simplifying developer experience and accelerating customer time-to-value.
