Developed and integrated a Circle Placeholder Shape Component for the Lemoncode/quickmock repository’s Low-Wireframe Library, focusing on early-stage mockup enhancement. The work encompassed creating an SVG asset, implementing component logic in TypeScript, and ensuring seamless rendering and integration with the existing shape model and gallery data. Leveraging front-end development skills with React and Konva, the component was delivered as an end-to-end feature, enabling immediate use in design prototypes. This addition improved prototyping speed and design-system consistency, supporting more efficient design reviews. The approach demonstrated thoroughness in both asset creation and UI integration, with traceable commits for maintainability.
