Developed and delivered the Gas Plasma color theme and file icon theme for the Zed Extension Marketplace, focusing on expanding visual customization and branding options for extension users. This work, implemented in the zed-industries/extensions repository, integrated external GasPlasma-theme assets to ensure consistent UI theming across the marketplace. Leveraging skills in Git, UI/UX design, and front end development, the implementation emphasized traceability by referencing external repositories and tags within commit metadata. No major bugs were addressed during this period, as the primary focus remained on feature delivery and UI consistency, enhancing user engagement and supporting a cohesive extension ecosystem.
