What I'm looking for

I seek a role building production-grade predictive models and analytics pipelines, collaborating cross-functionally, mentoring juniors, and driving measurable operational improvements using Python, SQL, and BI tools.

I am a data scientist with experience building production-ready predictive models, automated reporting pipelines, and interactive BI dashboards. I have used Python, SQL, Power BI and cloud storage (AWS S3) to streamline workflows and uncover operational insights.

At Verizon I implemented automation and predictive algorithms that improved process efficiency by 30% and mentored junior analysts while contributing to production-grade pipelines and unit-tested Python tools. I also delivered forecasting and fraud-detection solutions at Fidelity and reduced reporting cycles through ETL and dashboard automation at Wipro.
