Contributed to marimo-team/marimo by delivering interactive data visualization features and developer experience improvements over three months. Built unified, reactive selection capabilities across all Plotly chart types, enabling users to retrieve and analyze data points interactively in Python. Enhanced both frontend and backend systems using JavaScript, TypeScript, and Python, integrating robust selection modes and ensuring seamless feedback between UI and analytics workflows. Improved CI/CD pipelines and code quality by automating linting, formatting, and version control checks, while documenting onboarding and API usage. Strengthened reliability through expanded test coverage, regression tests, and WebSocket handling, supporting stable releases and efficient developer onboarding.

Apr 1, 2026April 2026 monthly highlight: Delivered end-to-end reactive selection across all Plotly chart types in marimo, enabling interactive data retrieval and feedback across lines, bars, waterfalls, violins, areas, boxes, funnels, and funnelareas. Implemented single-click, click, box and lasso, and range-based selection to streamline data exploration. Backend and frontend jointly updated to support per-type selection paths, with tests and examples to validate and demonstrate capabilities. Documentation updates ensure API clarity and ease of adoption. This work improves data discovery, supports faster decision making, and provides a consistent, data-rich UX across visualization types.

Mar 1, 2026March 2026 delivered major data exploration features and stability improvements across marimo, enabling faster analysis and a smoother developer experience. Key features include reactive scatter plot selections across ScatterGL and Plotly, plus interactive histogram bin selections that feed selected data back to Python. Stabilization efforts reduced dev-time friction by preserving api.yaml versioning, and hardening Ty LSP startup/diagnostics with regression tests and robust WebSocket handling. Demonstrated expertise in Plotly integration, LSP reliability, testing, and documentation, delivering clear business value and reliable analytics workflows.
