Worked on the malloydata/malloy repository, delivering enhancements across backend, frontend, and documentation within a month. Focused on improving array cell rendering in UI tables, enabling comma-separated display for arrays and consistent formatting for numbers, dates, and nulls, all supported by comprehensive tests and Storybook coverage. Upgraded the DuckDB backend to use @duckdb/node-api with Promise support, improving streaming, type handling, and array order stability. Enhanced numeric and currency scaling with expanded syntax and bigint formatting. Fixed SQL generation to ensure correct ROW_NUMBER usage for composite ordering, and updated documentation to clarify label rendering tags. Used TypeScript, SQL, and React.
2026-01: Delivered rendering, backend, and formatting enhancements that reduce errors and boost data exploration speed. Key achievements: (1) array cell rendering improvements with plain arrays rendered as comma-separated strings and proper formatting for numbers, dates, and nulls, backed by tests and Storybook coverage; (2) DuckDB backend upgrade to @duckdb/node-api with Promise support, improved UNNEST ordering for DuckDB 1.4, and streaming/type handling improvements; (3) numeric/currency scaling enhancements with versatile shorthand/verbose syntax, broad scale support, and bigint formatting with tests; (4) SQL generation fix to emit a single ROW_NUMBER() for composite ordering with regression tests; (5) documentation updates clarifying label rendering tags.
