PROFILE
Mary-ellen
Worked extensively on the lockss-daemon repository to deliver robust content ingestion and archival workflows for academic publishers. Over 18 months, developed and maintained ingestion pipelines, metadata management, and status lifecycle automation, enabling timely processing and reliable preservation of scholarly content. Leveraged Python, Shell scripting, and AWK to modernize SOAP client integrations, automate configuration management, and enhance data processing observability. Focused on cross-publisher orchestration, release engineering, and database management to ensure production-ready deployments and minimize operational risk. Addressed data integrity through manifest expansion, status corrections, and plugin tooling, resulting in scalable, auditable ingestion pipelines and improved content availability across multiple years.

Mar 1, 2026March 2026: Delivered a comprehensive Crawling Status Lifecycle Update for 2026 publishers in lockss-daemon. The work consolidates the crawling workflow to halt crawling for problematic articles by changing status from deepCrawl to frozen, updates source content entries to reflect 2026 crawling status, shifts to actively crawling the latest content, and marks content as production-ready for multiple publishers. This aligns with 2026 publishing requirements and improves data freshness, reliability, and downstream processing across publisher workflows. Technologies and skills demonstrated include crawling workflow orchestration, lifecycle management, and metadata-driven production gating.

Jan 1, 2026January 2026: Focused on enabling a production-ready 2026 content ingestion workflow in lockss-daemon and preserving data integrity ahead of a plugin release. Delivered ingestion readiness by updating publisher statuses to readySource and advancing from crawling to processing, with production releases tied to explicit commits. Implemented a Legacy Ubiquity Content Freeze to prevent crawling or modification of older content in anticipation of the new plugin release, safeguarding against conflicts. No explicit bug fixes were required this month, but the work significantly reduces operational risk by stabilizing data flows and establishing clear release traceability. Demonstrated capabilities include ingestion workflow orchestration, crawl-to-processing pipelines, data integrity preservation, and robust release hygiene using commit-driven changes.
