What I'm looking for

I seek analytics roles where I can build dashboards, automate reporting, and partner with stakeholders to drive measurable business impact and career growth.

I am a Business Intelligence Analyst with three years of experience in data analysis, visualization, and reporting, proficient in Python, SQL, Power BI, Tableau and Excel. I build interactive dashboards, automate ETL and reporting processes, and provide KPI-driven recommendations that improve operational efficiency and support strategic decisions.

My projects include sales forecasting, customer segmentation, and telecom data optimization where I proposed targeting models that cut communication waste and delivered dashboards that reduced manual reporting by 40% and improved operational efficiency by 15%. I collaborate with stakeholders to translate business needs into measurable analytics solutions.
