What I'm looking for

I seek a data-driven role where I can build end-to-end analytics and ML pipelines, collaborate cross-functionally, and deliver scalable insights in healthcare, finance, or regulatory domains while applying cloud and BI technologies.

I am a results-driven Data Scientist / Data Analyst with over five years of experience in machine learning, predictive modeling, data architecture, and visualization. I have designed, developed, and deployed computationally complex data solutions across healthcare, finance, and regulatory reporting to deliver high-quality, actionable insights.

At Mantech and prior roles at United Health Group, Bloom Energy, and Cisco, I built end-to-end pipelines, optimized processing (for example reducing pipeline time from 4 hours to 45 minutes), and implemented Salesforce automations that cut manual entry by 45% while improving lead-to-opportunity conversion. I am proficient in Python, R, SQL, AWS (S3, EMR), Hadoop ecosystem, Tableau and Power BI, and I collaborate cross-functionally to translate business requirements into dashboards, models, and measurable outcomes.
