Erik Hanson developed and maintained core features across the PKP repository ecosystem, focusing on backend workflows for academic publishing. He engineered automated DOI assignment, peer review progress tracking, and the publish-review-curate workflow in pkp-lib and pkp/ojs, using PHP, JavaScript, and Vue.js to enhance traceability and data integrity. Erik’s technical approach combined schema migrations, API development, and event-driven logic to streamline editorial processes and improve metadata reliability. He regularly synchronized dependencies and submodules, ensuring stability and maintainability across OJS, OPS, and OMP. His work demonstrated depth in backend development, database design, and cross-repository coordination for sustainable platform evolution.
March 2026: Delivered cross-repo enhancements for PKP projects, focusing on streamlining peer review visibility and keeping dependencies up to date.

February 2026 delivered substantial enhancements to the platform’s peer review workflow and artifact traceability, focusing on quality, accuracy, and maintainability across core PKP projects. Key outcomes include enhanced peer review outputs with author responses and correct endpoint data, the introduction of DOIs for peer reviews and author responses across multiple repositories, and coordinated submodule/dependency updates to capture the latest fixes and features. A data-accuracy issue was resolved by fixing a DOI management filter typo in the review_round table, and a deduplication improvement reduced the presentation of duplicate open peer reviews. The work improves data integrity, governance, and business value by enabling more traceable, accessible, and reliable review records while keeping dependencies current for quicker iteration and deployment.

Month: 2025-11. Summary: Delivered cross-repo stability through coordinated Submodule Dependency Updates across pkp/ojs, pkp/omp, pkp/ops, and pkp/pkp-lib, totaling 14 update commits to align with upstream libraries. Introduced a new Public Peer Reviews API for Publications in pkp/omp to enable programmatic access to peer-review data. Fixed a reliability issue in OrcidManager by ensuring getApiType returns an empty string when the API type is missing, reducing null-reference risks. Overall, these efforts improved stability, maintainability, and data accessibility, while reducing upgrade risk across the PKP stack.
