May 1, 2025May 2025 performance summary for broadinstitute/juniper: Delivered significant data-import enhancements, migration reliability improvements, and automation refinements that collectively improve data integrity, user communications, and release quality. Key features delivered: - Data Import Improvements: associate created enrollees with import items, enable sending emails to imported participants, and handle pre-enrollment surveys during participant import. (JN-1674, JN-1673) - Pepper Data Migration Improvements: adjust task finding/import to use creation time and enhance data translation for repeated questions and date formats. (JN-1675) - Email Notification: accountUsername added to email notifications with a getUsername helper; strip proxy suffix; include tests. (JN-1678) - Clear Enrollment Parameters on Load: UI option to clear enrollment parameters on load via pre-enrollment shortcut modal. (JN-1688) - Recurring Tasks Trigger Configuration: allow triggering recurring tasks (surveys) based on completion date or creation date; update UI accordingly. (JN-1687) - SonarCloud CI/CD Workflow Improvements: refactor workflow to correctly set branch parameters for analysis based on current and default branches. (JN-1693) Major bugs fixed: - Import Email De-duplication: ensure only one invitation email is sent per unique participant user during data import. (JN-1689) - SQL NOT_EQUALS NULL-Safety Fix: fix NOT_EQUALS operator for nullable fields by using IS DISTINCT FROM; add tests for null survey answers. (JN-1679) - Reminders: independent processing: fix reminder processing so distinct reminders for different tasks are processed independently; avoid cross-task mixing. (JN-1690) - Longitudinal Surveys: prevent edits on removed: ensure only the most recent non-removed longitudinal survey task can be edited; prevent edits to outdated/removed survey data. (JN-1686) Overall impact and accomplishments: - Improved reliability and data integrity across imports, migrations, and survey workflows, reducing manual rework and user escalation. - Reduced email spam risk through de-duplication, and improved user communications via accountUsername enhancements. - Strengthened automation and release quality through CI/CD workflow improvements and better task scheduling logic. Technologies/skills demonstrated: - Data engineering patterns (task/creation-time logic, data translation for repeated questions and date formats) - Email workflow enhancements and robust testing - UI/UX considerations for enrollment flows (Clear Parameters on Load) - CI/CD improvements with SonarCloud, and enhanced test coverage for nullability and edge cases
