Rockstar🎓
Top SchoolJi-hun Cho is a pragmatic software engineer with seven years of experience building scalable search and content systems, most recently contributing to gRPC Java at Google. Based in the San Francisco Bay Area, he has driven measurable improvements in search relevancy, latency, and caching through stateless algorithms, distributed ETL pipelines with Spark, and near real-time indexers. At Simply Hired he led initiatives that improved accuracy by 30%, reduced refresh intervals by 70%, and cut search latency by a third, blending algorithmic rigor with production-minded design. Known for a "do the right things right" ethos, he favors configurable, low-friction systems—evident in his work on streaming parsers, unified schedulers, and A/B reporting frameworks.
