Apr 1, 2026April 2026 monthly summary for SORMAS-Project: Delivered targeted data-capture and user-experience enhancements to strengthen malaria/dengue surveillance and serotype data handling. Key features include serotype handling, pathogen test enhancements, and malaria/dengue data tracking with updated DB schema and fields, implemented across a cohesive set of changes. UI and data-entry improvements increased data quality and usability with visibility checks, longer text fields, travel-related UI, and flexible data-entry scenarios (including pregnancy/postpartum). A database upgrade logic fix ensured the serotype text column is added correctly and data is migrated reliably across versions. Overall, these changes improve surveillance accuracy, clinician-facing messaging, and system stability, enabling faster decision-making and better compliance with data standards.

Jul 1, 2025July 2025: Delivered three user-facing features that strengthen data entry, data mapping, and analytics, while stabilizing the codebase with key bug fixes that improve reliability and compliance readiness. Key features: (1) Luxembourg Entry Date field refined to be visible and required only for foreign Luxembourg cases with specified invasive diseases, reducing data-entry errors; (2) IPI Doctor's Declaration feature introduced with deceased date in external messages, reporting agent details in notifiers, and enhanced mapping/schema support for unknown symptoms; (3) Sample Dashboard enhancements enabling environment-based filtering for human vs. environmental samples with the map/data provider respecting the selection. Major bugs fixed: (1) Pathogen Test Data Initialization and Drug Susceptibility Validation corrected to prevent null pointers and incorrect UI state; (2) ANTIBIOTIC_SUSCEPTIBILITY exclusion handling updated across disease classifications in tests; (3) Adverse Events Sorting Mapping fix to ensure accurate sorting by report date, adverse events, immunization UUID, disease, and primary vaccine name; (4) Death Date propagation fixed from personCreated to person during creation. Overall impact: improved data integrity, UI correctness, and test stability, enabling more reliable regulatory reporting and informed decision-making. Business value: higher data quality, reduced manual rework, and faster onboarding for new data-entry workflows. Technologies/skills demonstrated: backend data mapping and schema evolution, UI state management, test-driven development and maintenance, environment-aware data filtering, and robust data validation.
