Worked on the primer/react repository to deliver scenario-based pattern retrieval for the MCP server, focusing on enhancing the pattern registry and tool logic to prioritize scenario patterns over generic UI patterns. Utilized Node.js and TypeScript to extend server-side pattern tooling, ensuring that context-relevant patterns are surfaced more effectively for developers. Updated documentation to provide clear guidance on adopting the new scenario patterns, supporting a smoother transition for users. The work addressed the need for more targeted pattern retrieval, aligning with product goals and improving developer experience. Demonstrated proficiency in API development, MCP, and documentation tooling throughout the feature implementation process.
