What I'm looking for

I seek a data role where I can build actionable dashboards and KPIs, influence decisions, collaborate cross-functionally, and grow in analytics and BI leadership.

I am a mid-level Data Analyst with hands-on experience delivering end-to-end analytics solutions across telecommunications, retail, ride-hailing, sales, logistics, healthcare, and email marketing domains.

I build executive-ready dashboards and KPIs using Power BI (DAX, Power Query, data modeling) and SQL, translating complex datasets into actionable insights and business storytelling.

My projects include customer churn analysis, ride-hailing performance, retail sales and pricing analysis, email marketing campaign evaluation, sales pipeline forecasting, logistics performance monitoring, and healthcare service utilization.

I hold certifications including SQL Server Developer, Associate Data Analyst, and Analyst in Power BI from DataCamp, and I am available for new opportunities where I can apply metric design, segmentation, and operational analytics to drive measurable business impact.
