Over four months, contributed to the rice-apps/thea-aa repository by building and enhancing a data pipeline for environmental compliance. Developed Django-based data models and REST APIs for emission events and Superfund sites, integrating automated data ingestion using Selenium and Django-crontab for scheduled scraping and import of EPA and TECQ datasets. Improved data integrity through model upgrades, database migrations, and enforcement of unique identifiers, while aligning frontend Svelte components and map visualizations with backend changes. Leveraged Python, SQL, and Pandas to streamline data processing, ensuring reliable analytics, geospatial accuracy, and maintainable code through repository hygiene and migration corrections.

Apr 1, 2025April 2025: Implemented end-to-end enhancements to the Superfund data pipeline and map visualization, integrating scraped latitude/longitude into site records, merging coordinates with existing data, and removing outdated records before re-import. Updated the map component to render markers for Superfund sites and emission events based on coordinates, improving geospatial accuracy and decision support. Performed a Django migrations rollback/correction to restore and stabilize schema for critical models by restoring initial migrations and creating new ones for SuperfundSite and EmissionEvents, ensuring data integrity and smoother future migrations.

Mar 1, 2025Concise monthly summary for 2025-03 focusing on business value and technical achievements. Key features delivered: - Emission Events Data Model Upgrade (contaminants and authorizations): performed a database migration to remove obsolete emission event fields and add new fields for contaminants and authorizations. Frontend components for emission events and map display were updated to align with the new structure and coordinates. As part of cleanup, the temporary Excel export file was removed. Major bugs fixed: - No major bugs reported this month; one quick fix was merged as part of the upgrade (commit referenced below). Overall impact and accomplishments: - Strengthened data integrity and compliance readiness by enabling richer data capture for emission events, contaminants, and authorizations. - Enabled more accurate analytics and reporting through the updated data model and synchronized frontend visuals. - Reduced technical debt and potential data leakage by removing legacy Excel export artifacts. Technologies/skills demonstrated: - Database migrations and data model evolution - Frontend/UI alignment with backend changes and map integration - Data cleanup and artifact removal - Version control discipline with targeted fixes (quick fix commit) Commit reference associated with this work: - 6248ae0670790c7e52c61abb1e5a9e286b2a8acd

Feb 1, 2025February 2025: Delivered end-to-end automated data ingestion for EPA Superfund and TECQ data in rice-apps/thea-aa. Implemented a Selenium-based scraper to download Excel data, convert to CSV, and orchestrate runs via a Django-crontab scheduled task. Extended EmissionEvents data models and serializers to accommodate new fields and updated the import script to handle TECQ data fields. These changes enable automated, timely, and reliable data ingestion for downstream analytics and reporting, reducing manual effort and improving data freshness and consistency.
