Ellylai
Ellyse Lee contributed to the ScottyLabs/cmumaps repository by engineering robust backend features for event data processing, floorplan serialization, and scalable data storage. She enhanced the data export pipeline using Python and TypeScript, introducing selective serialization and enriching building models with OpenStreetMap IDs. Her work unified authentication flows across HTTP and Socket.IO using Clerk, centralized API integration, and migrated floorplan data storage to AWS S3 for improved scalability. Ellyse also streamlined developer onboarding through updated documentation and code cleanup. Her contributions demonstrated depth in backend development, data serialization, and cloud integration, resulting in more reliable analytics and maintainable infrastructure.

Jul 1, 2025July 2025 performance summary for ScottyLabs/cmumaps. Focused on floorplan data serialization enhancements and expanding the API surface for graph-level access. Delivered an all-graph export script and a new API endpoint to retrieve all nodes; improved CLI with argparse, reduced duplication in data fetching, and added coordinate transformation for geo coordinates. Performed maintenance updates (submodule update and dependency bumps) and cleaned up the codebase by removing redundant endpoints and refactoring the serializer. These efforts increased data accessibility, accuracy, and maintainability, enabling downstream apps to render complete floorplans with reduced integration risk.

Jun 1, 2025June 2025: ScottyLabs/cmumaps delivered key data serialization enhancements and floorplan endpoints, significantly improving data export fidelity and integration readiness. Work focused on expanding the serialization framework, enriching the Building model with osmId, and exposing robust floorplan endpoints, while addressing a TypeScript syntax issue to improve build reliability. These changes enable selective, per-floorplan serialization and more complete exports (buildings, floors, rooms) to downstream analytics and clients.

Apr 1, 2025Month: 2025-04 — Delivered critical data processing improvements for ScottyLabs/cmumaps, focusing on Spring Carnival event data. Key changes include fixing the data source path for carnival_events.json to cmumaps-data/spring-carnival/, and introducing a tagging mapping function to categorize events by tracks, removing direct tag mapping from the event model to improve categorization reliability and business insights. These changes reduce data sourcing errors, enhance event-driven analytics, and lay groundwork for scalable event tagging. Result: higher data quality for carnival events, faster refresh cycles, and clearer business insights for stakeholders.
