May 2026 focused on enabling browser-based data exploration by delivering remote DuckDB queries in WASM notebooks and polishing tutorial documentation. The work directly supports business value by allowing analysts to run SQL against remote CSV, Parquet, and JSON datasets directly in the browser, reducing data transfer, speeding prototyping, and improving reproducibility. Delivered a robust DuckDB WASM fallback layer with HTTP-based queries for remote data sources, end-to-end remote data access via a Python fetch path, and validated the workflow with unit tests and a WASM playground demo. Tutorial notebooks were polished with an external dependencies section and clearer Markdown guidance. Core technologies demonstrated include Pyodide, DuckDB-WASM, sqlglot for SQL analysis, urllib-based data fetching, and pandas interoperability.
