Over a three-month period, contributed to the hartwigmedical/actin and hartwigmedical/scripts repositories by building clinical data evaluation features and automation tools. Developed a comorbidity-based rule engine in Java and Kotlin, refactoring legacy complication-based logic to improve risk assessment and maintainability. Enhanced API ergonomics by exposing enum text fields for easier integration. In hartwigmedical/scripts, implemented bash and shell scripts for patient data sharing event tracking, semantic version tagging, and automated Git branch cleanup, strengthening data governance and streamlining release workflows. Focused on code organization, error handling, and version control, the work emphasized maintainable automation and robust clinical data processing solutions.
Monthly performance summary for 2026-04 (hartwigmedical/scripts). 1) Key features delivered: - Patient Data Sharing Event Tracking: Added tracking events to the sharing scripts and the EMC script to monitor and log patient interactions, enabling improved auditability and data governance. - Semantic Version Tagging Script: Implemented a script to generate and push semantic version tags (major/minor/patch/beta) with validation, along with improvements to CLI behavior (executable push, usage messaging, and branch-change checks). - Git Branch Cleanup Automation Script: Automated cleaning of merged or deleted Git branches to reduce repository clutter and improve development hygiene. 2) Major bugs fixed: - crash on missing beta version: Robust error handling, usage guidance, and safe defaults in the semantic version tagging script, preventing crashes when beta data is missing or arguments are incomplete. - Ensured versioning checks target the current branch instead of main, improving reliability in multi-branch workflows. 3) Overall impact and accomplishments: - Strengthened data governance and auditability through event tracking for patient data sharing. - Streamlined release management and version control with robust semantic tagging and safer branch hygiene automation. - Reduced manual maintenance overhead and improved developer experience via clearer CLI usage and safer defaults. 4) Technologies/skills demonstrated: - Scripting and automation (likely Python/Shell), Git workflows and semantic versioning, CLI/UX design, error handling, and integration of automation into release processes.

In August 2025, delivered a comorbidity-based evaluation rule system for ACTIN, refactoring the evaluation logic to replace complication-based rules with a more comprehensive comorbidity-based approach. Deprecated older rules (HAS_ANY_COMPLICATION, HAS_COMPLICATION_WITH_ANY_ICD_TITLE_X) and introduced HAS_COMORBIDITY_WITH_ANY_ICD_TITLE_X to assess risk across all comorbidities. This work, tracked under ACTIN-2388, improves decision-support accuracy, reduces maintenance burden, and sets the groundwork for scalable ICD-title coverage.
