Greg Wilson contributed to the Plotly open-source ecosystem by building and refining core features across plotly.py, plotly.js, and Dash. He focused on code generation, validator optimization, and CLI tooling, using Python and JavaScript to streamline build processes and improve maintainability. In plotly.py, Greg modernized build tooling with uv and ruff, enhanced type safety, and reduced package sizes through validator caching. He improved documentation clarity in plotly.js and strengthened type annotations and static analysis in Dash. His work emphasized robust CI/CD practices, code formatting with Black, and clear documentation, resulting in more efficient development workflows and reliable releases.

August 2025: Focused on strengthening developer experience and documentation for plotly.js. Delivered targeted clarifications and refactors in documentation related to sourcetype formats for Map/Mapbox and Parcats hover flags, along with formatting improvements to ensure consistent API usage. A small Markdown tidy-up commit supported these changes. These efforts reduce onboarding time, prevent misinterpretations, and improve consistency for users employing Map/Mapbox sourcetypes and Parcats features across the repository.

February 2025: Delivered targeted code and test improvements across plotly.py and plotly.js. Key features include a Codebase Refactor for Maintainability and API Consistency in plotly.py (code generation size reduction and API alignment) and Font Options Description Optimization across both libraries to shrink bundle sizes. Major bug fixes include PyArrow Timezone Handling Bug Fix and Test Stability/CI improvements enhancing test reliability and CI stability. Business impact: smaller bundles speed up load times and reduce bandwidth, more robust tests, and improved maintainability; cross-repo consistency enhanced with shared schema updates. Technologies demonstrated: Python/JS development, code generation, PyArrow, test engineering, CI/CD, JSON serialization, and schema management.
