Summary
🤩
Rockstar🎓
Top SchoolRichard Xia is a software engineer in San Francisco with 16 years of experience building reliable systems across low-level hardware tooling, data engineering, and full-stack applications. He currently works at Flow Labs and has deep open-source contributions to prominent projects like the Rocket Chip generator and LLVM/CIRCT, reflecting strength in system-level design and compiler/IR optimizations. Past roles at KeepTruckin centered on scaling ETL pipelines and Snowflake warehouses, plus productionizing self-serve data tooling on Kubernetes and Airflow. His GitHub work shows both hardware-software co-design (address decoders, atomics, debug modules) and tooling/DevOps chops (robust test infrastructure and OpenOCD integration). Comfortable from C# web stacks to Python data platforms and backend compiler code, he bridges product teams and infrastructure to deliver pragmatic, testable solutions. He holds a Computer Engineering degree from UT Dallas and tends to favor durable, automatable fixes that improve long-term reliability.
