What I'm looking for

I seek a senior analytics role in healthcare or enterprise settings to optimize systems, build end-to-end reporting and dashboards, lead data integrations, and collaborate with cross-functional teams for measurable business impact and continuous learning.

I am a Senior Business Systems Analyst and data-driven healthcare associate data scientist with extensive experience optimizing healthcare systems, digital communication workflows, and enterprise reporting.

At UnitedHealth Group and Cotiviti I led business process analysis, designed and maintained ETL pipelines with SSIS and Visual Studio, integrated RESTful APIs, and built interactive Power BI and Tableau dashboards that delivered actionable insights to stakeholders.

I specialize in SQL, Snowflake, SSRS, ServiceNow, NLP techniques, predictive modeling (regression, decision trees, random forest), and advanced data cleansing and validation to ensure high data integrity for financial and communication analysis.

I partner with cross-functional teams to perform UAT, root cause analysis, documentation, and process improvements; I am driven to apply analytical rigor and problem-solving to improve operational performance and measurable business outcomes.
