Rockstar🎓
Top SchoolJeremy Zhao is a Senior Engineer based in Beijing with 11 years of experience building high-performance backend systems and mobile platforms, currently at Baidu. Trained at Tsinghua University with a master's in computer science, he has strong C/C++, Java, Hadoop expertise and has shifted focus to Android and iOS since 2015. He contributes to prominent open-source projects—most notably improving RocksDB’s Java JNI stability and performance and enhancing Apache TinkerPop and HugeGraph for scalable graph workloads. His work bridges backend development and DevOps, from fixing concurrency and cache issues in databases to streamlining CI/CD for large graph systems. Known for pragmatic problem-solving, he combines low-level systems insight with production mobile development experience. An interesting detail: he’s tackled both language-boundary bugs in native Java/C++ integration and large-scale deployment automation, a blend that makes him effective across the stack.
