Makena Dettmann developed and maintained data ingestion, processing, and visualization pipelines for the ber-data/bertron and bertron-schema repositories over four months. She implemented Python scripts for API integration and data cleaning, producing structured JSON and CSV artifacts to support downstream analytics. Her work included integrating EMSL sample data, rendering interactive map visualizations using JavaScript and Leaflet.js, and ensuring data provenance through overlay layers with project links. Makena also addressed data integrity by correcting endpoint references and file path resolutions, improving onboarding and reliability. The engineering demonstrated depth in data engineering, frontend development, and cross-repository documentation, resulting in robust, maintainable workflows.

June 2025: Delivered two targeted data and visualization fixes across bertron-schema and bertron, improving data integrity and map UI reliability. EMS Example Data Source Correction fixed a misreferenced data origin in emsl-example.json, ensuring example datasets load from the correct source. Map Data Path Resolution Fix corrected data file path resolution by prepending '/map' to latlon_project_ids.json and all_emsl_samples.json, ensuring map markers render reliably. These fixes reduce support overhead and improve onboarding accuracy, with clean cross-repo commit updates and minimal code changes.

April 2025 — bertron: Key EMSL data integration and map visualization delivered. Implemented EMSL sample data pipeline by fetching and processing MONet JSON, adding EMSL sample CSV, and rendering EMSL markers on the map via overlay layers with project links. These changes enable users to visually explore EMSL samples and access related project information directly from the map, improving data provenance and decision support. No major bugs were reported this month; the work focused on end-to-end data ingestion, visualization stability, and groundwork for EMSL-driven analytics. Technologies demonstrated include JSON data processing, client-side mapping, CSV integration, and overlay-layer visualization.

March 2025 performance summary focusing on the ber-data/bertron and ber-data/bertron-schema work. Key features delivered include an end-to-end EMSL data ingestion and processing pipeline that fetches and processes EMSL data via API, cleans and renames fields, and outputs a structured JSON artifacts set (emsl_data.json, emsl_samples.json, emsl_datasets.json) in bertron. A separate repository, bertron-schema, received foundational project documentation with a placeholder README.md to establish onboarding and contract documentation. No major bugs were reported this month. Overall impact includes faster time-to-data for EMSL inputs, a standardized data schema to enable downstream analytics, and a clearer project scaffold to support collaboration and onboarding across both repositories. Technologies and skills demonstrated include Python scripting for API calls, data cleaning and transformation, schema-driven data structuring, JSON artifact generation, and lightweight documentation scaffolding with Git version control across multiple repos.
