Summary
🤩
Rockstar🎓
Top SchoolGarrett Wang is a Senior Software Engineer at Google with nine years of experience building high-performance infrastructure, profiling tools, and data processing pipelines. He combines deep systems-level expertise—exemplified by contributions to pprof and a C++/cache-optimization research project—with production experience migrating terabyte-scale MapReduce jobs and designing scalable load-testing frameworks. At Google he focuses on performance and efficiency tooling, automated performance insights, and back-end systems for large product surfaces like YouTube social infrastructure. Garrett’s background blends academic research (a system that improved SPEC CPU2006 benchmarks) with pragmatic engineering at scale, including shipping substantial C++ code and designing robust rollback and testing mechanisms. Based in Sunnyvale, he’s comfortable across C++, Java, Python and pipeline frameworks, and brings a knack for translating low-level performance insights into usable developer tooling. Beyond the obvious, he’s proven at both inventing profiling improvements and operationalizing them into teams’ workflows.
