4G/5G Core System. Software design from backend Python system, to frontend web browser thin client. I built from scratch the UPF data plane with P4 SmartNIC hardware acceleration. The data transmission was a 67% increase and optimized from 6 Gbps to 10 Gbps. The optimization scheme also obtained patents in Taiwan, US, and Europe.

of open-source AI community. PROJECT Next-Generation ETL Framework for Data Science Team 2022/7-2022/12 Goal: Design a lightweight ETL python framework enabling data scientists to seamlessly deploy their pandas/SQL processes to airflow in a maintainable format. Reduce the maintenance and optimization cost of AI projects with integration of customizable data validation, metadata registration, and time/memory-profiling tools. Ensure flexibility and extensibility in pandas-like packages (such as CuDF, Polars, PySpark, etc) for future parallelizability, targeting 1000X speedup. Responsibility: Coordinate the design and development of ETL framework
