• Senior undergraduate Computer Science student at National Cheng Kung University (NCKU), Taiwan.
• Research Assistant at Secure Systems Lab, National Taiwan University, under Prof. Shih-Wei Li.
• Research focus: para-virtualization (virtio) and system performance optimization for Confidential Computing (CVMs), with ongoing work analyzing and improving the virtio-vsock communication interface.
• Interested in database storage systems, currently building a series of DuckDB extensions to explore storage internals and observability.
• Strong interest in virtualization, Linux kernel, and system-level performance engineering.

• Moonlink
  Iceberg-native ingestion engine enabling streaming inserts and upserts for lakehouse architectures.

  • Supports ingestion from Postgres CDC, Kafka event streams, and OTEL telemetry data.
  • Uses buffering, caching, and indexing to keep Iceberg tables read-optimized without heavy maintenance or compaction.

• DuckDB Community Extensions

  • duckdb-table-inspector
    • Storage observability for DuckDB: inspect database, table, and column-level usage, compression, indexes, metadata, and free blocks.
  • duckdb-query-condition-cache
    • Predicate-aware vector pruning for recurring filters, skipping non-qualifying vectors before decompression and predicate evaluation.

Always open to research, open-source collaboration, and systems engineering opportunities.
