PROFILE
Kimiyasu Morikawa
Worked on the NYPL/drb-etl-pipeline repository over four months, delivering features that enhanced semantic search, data processing, and user experience for library catalog systems. Leveraged Python, JavaScript, and Elasticsearch to implement a research assistant with semantic vector search, modularized backend code, and improved API endpoints for clarity and maintainability. Addressed privacy by removing analytics integrations and strengthened type safety in React components. Enhanced CI/CD reliability and documentation hygiene, while optimizing model performance and response formatting. Fixed user experience bugs related to state preservation and streamlined deployment workflows, demonstrating a methodical approach to backend development, automation, and workflow optimization.
