Summary
Cheng Chi is a Senior Software Engineer specializing in web application performance with 15 years of experience driving capacity planning, scalability testing, and end-to-end performance diagnostics across J2EE stacks. Based in San Francisco, he has led performance engineering at Adobe and StubHub, combining profiling, heap/thread dump analysis, and Apache/GC tuning to find deep code-level bottlenecks. He designs load models and automation frameworks (WebDriver + TestNG, JMeter, LoadRunner, SoapUI) and has built custom tooling like the ExPerT automation framework to accelerate performance sanity checks. Comfortable working in scrum teams, Cheng pairs hands-on debugging with cross-team collaboration to translate metrics into actionable fixes. A former telecom test engineer, he brings protocol-level rigor and a penchant for scripting (Ruby, Java, C, shell/awk) that surfaces non-obvious systemic issues before they reach production.
