Developed and delivered the Pearish Theme Extension for the zed-industries/extensions repository, introducing a warm, earthy color palette with both light and dark variants to enhance UI consistency and support branding requirements. The work focused on front end and theme development, leveraging extension architecture and theming pipelines to streamline customization and improve user experience. Version control was managed using Git, and configuration was handled with TOML, ensuring maintainability and clear documentation. The implementation included a single, well-documented commit that provided a comprehensive feature summary and repository context, resulting in faster theming workflows and improved accessibility without addressing major bugs during this period.
