Notable open source projects that you contribute to. Add URLs, one per line.

I was one of the original co-authors of the pandas library from before it was open-sourced to 2014.

Serverless billion-scale vector search for AI applications
Chang She

From recommendation systems to LLM-based applications, vector search is a critical component of the modern AI workflow. Existing vector solutions are complicated to use, hard to maintain, and cost too much. LanceDB is a free open-source vector store that can perform low latency vector search on billion-scale vector datasets on a single node. LanceDB is powered by Lance format, a modern columnar data format for machine learning and data science. Compatible with pandas/polars/duckdb, Lance format supports vector index, predicate pushdown, and random access performance 2000x faster than parquet.
