During March 2025, Bigdadbear developed the Primer::Alpha::Banner Upsell Scheme within the primer/view_components repository, focusing on enabling targeted upsell messaging for marketing campaigns. They implemented new CSS classes and component logic to support the upsell scheme, allowing banners to display specific styles and icons based on marketing requirements. The work included writing tests and creating previews to ensure a smooth rollout and support for various use cases. Utilizing CSS, Ruby, and front-end component development skills, Bigdadbear’s contribution provided a foundation for marketing-driven features, though the scope was limited to a single feature with no recorded bug fixes during this period.
