Worked on the tuva-health/tuva and tuva-health/docs repositories to deliver a provider attribution feature supporting yearly and current attribution, provider ranking, and taxonomy-based classification. Enhanced data quality by rebuilding provider ranking logic, standardizing column names, and improving date build reliability with staging and calendar joins. Addressed multiple bugs related to variable handling, terminology mapping, and clinical gating, while also adding descriptive step documentation and holistic cohort reporting. Refactored YAML models and applied linting for codebase stability. Contributed to documentation and dashboard integration using SQL, YAML, and React, supporting healthcare analytics and enabling more robust, maintainable data engineering workflows.
