PROFILE
Kimiyasu Morikawa
Alea contributed to the NYPL/drb-etl-pipeline by building features that enhanced data processing and search capabilities over a three-month period. She implemented a semantic search feature using Elasticsearch and Flask, enabling vector-based queries across library catalogs and book contents. Her work included API development in Python and JavaScript, modularizing backend code for maintainability, and improving data extraction from chat completion responses to streamline downstream processing. Alea also addressed privacy by removing analytics integrations and improved documentation clarity. Her engineering demonstrated depth in backend and front end development, with careful attention to type safety, compliance, and scalable architecture throughout the project.
