What I'm looking for

I am looking for a collaborative BI/Data Analyst role where I can build scalable ETL pipelines, deploy predictive models, and deliver real-time dashboards to accelerate business decisions.

I am a results-driven data analyst with hands-on experience in BI, ETL automation and predictive modeling. I have improved reporting efficiency and reduced processing times—optimizing SQL and Talend workflows to accelerate insights and decision-making.

My technical work includes building dynamic Power BI and Tableau dashboards, deploying predictive models with FastAPI, and creating interactive analytical interfaces using Angular and Docker. I have delivered time series forecasting and a claims classification model with strong accuracy, and I have built tabular OLAP cubes and data warehouses to structure actionable analytics.

I enjoy solving business problems by translating data into clear, actionable insights and deploying scalable solutions. I work well in cross-functional teams, focus on robust data engineering and model deployment, and seek roles where I can continue to improve operational decision cycles and drive measurable business impact.
