Rory Kenny engineered robust data pipelines and documentation systems for the wellcomecollection/catalogue-pipeline and wellcomecollection/docs repositories, focusing on reliability, maintainability, and data integrity. He delivered end-to-end ingestion workflows, integrating AWS Lambda, Terraform, and Python to streamline data flow from source systems into Iceberg tables and Elasticsearch. His work included parameterized state machines, schema conversion between Pydantic and PyArrow, and comprehensive test coverage to ensure correctness. Rory also enhanced developer productivity by introducing local Lambda tooling, notebook-driven analysis, and detailed documentation with architecture diagrams. The depth of his contributions reflects strong backend engineering and a thoughtful approach to system design.
October 2025: Delivered notebook-driven data analysis capabilities for the catalogue graph and fixed cross-language title parsing parity in the EBSCO adapter. Reintroduced and stabilized critical notebooks for data ingestion, exploration, and interactive analysis, improving developer productivity and data workflows. Achieved cross-language consistency for MARC title parsing (Python vs. Scala), reducing downstream data quality issues. Overall, this work enhances data reliability, accelerates analytics, and supports better decision-making for catalogue data pipelines.

March 2025 performance summary for wellcomecollection/catalogue-pipeline: Delivered key features to increase determinism and observability of the catalogue ingestion workflow, fixed stability and correctness issues, and strengthened CI/CD and infrastructure. The catalogue-graph ingestor trigger is now parameterised by pipeline date for deterministic runs, with added monitoring across the ingestor trigger and loader outputs. Observability was extended with loader_monitor tests and a Terraform-based monitor Lambda, plus initial state machine step and CI involvement. The team addressed stability/quality issues in ingestor components, corrected policy naming, and performed pipeline hardening including renaming end index to record count and general formatting. A new script to deploy all ingestor Lambdas accelerates release cycles. Overall, these changes reduce failure modes, improve release confidence, and provide better operational insight for business decisions.
