Developed a plugin-driven TimeSeries CSV export feature across the perses/perses and perses/plugins repositories, enabling analysts to export time-series data directly from the UI with a single action. Leveraged React, TypeScript, and Material UI to integrate export actions into panel and chart headers, ensuring a unified and extensible user experience. Established a reusable export pattern that supports future plugin and data type extensions, while implementing robust Jest-based mocks to validate theming and context during testing. This work streamlined data extraction for analysis, reduced manual effort, and improved accessibility, reflecting a thoughtful approach to frontend development and plugin system integration.
