What I'm looking for

I’m looking for a Data Analyst role where I can own end-to-end SQL + BI workflows, design KPIs, and deliver actionable insights for churn, revenue, and customer experience—while partnering closely with teams to drive smarter decisions.

I’m a Data Analyst with hands-on experience delivering end-to-end data analysis projects using SQL, Power BI, and Google Sheets. I focus on data cleaning, data visualization, KPI design, and business insights that translate complex datasets into actionable recommendations.

In my work, I designed and monitored KPIs, identified a critical 82% revenue decline and analyzed root causes, and uncovered churn drivers in telecom and SaaS (including detecting 40%+ fiber churn and 52% SaaS churn). I also support data-driven decisions in customer service using CRM systems and databases, and I optimize marketing campaigns through social media KPI analysis.
