What I'm looking for

I seek a data-focused role where I can build scalable ETL and ML solutions, deliver automated dashboards, collaborate cross-functionally, and drive measurable business impact in a growth-oriented, data-driven team.

I am a results-driven Data Analyst with 4+ years of experience turning complex datasets into strategic business outcomes using Python, SQL, PySpark, Power BI and Tableau. I have a strong track record delivering predictive models, ETL pipelines, and automated dashboards that improved forecast accuracy by 18%, reduced reporting cycles by 50%, and drove ROI growth by 15%.

I collaborate effectively with executives, finance, and cross-functional teams to implement real-time KPI monitoring, data governance, and text analytics solutions that reduce costs and improve customer experience. I prioritize reliable data pipelines, clear documentation, and self-service analytics to accelerate decision-making and scale impact across organizations.
