What I'm looking for

I seek a data role where I can build automated ETL pipelines, deliver actionable dashboards, mentor teams, and drive measurable business impact in a collaborative, growth-oriented environment.

I am an analytical, detail-driven Data Analyst with over 3 years of hands-on experience transforming raw data into actionable insights that drive business decisions.

I build automated ETL pipelines, design interactive Power BI dashboards with DAX and KPIs, and implement statistical tests and predictive models to improve outcomes—delivering efficiency gains of 20–40% across projects.

My background includes cohort and churn analysis, A/B testing, web scraping, and forecasting; I have improved course completion, reduced attrition, and increased demand prediction accuracy through data-driven interventions.

I mentor learners, collaborate with cross-functional teams, and focus on reliable data workflows and clear visualizations to help organizations make faster, smarter decisions.
