Stop guessing and start growing with data-driven marketing insights.


I am a Marketing Data Analyst specializing in turning messy raw data into clear, actionable strategies. Using the precision of Python and the accessibility of Advanced Excel, I help businesses identify their most profitable segments, optimize their ad spend, and predict future trends.

What I Can Do For You:

  • Exploratory Data Analysis (EDA): Deep dives into your customer behavior and campaign performance.
  • Customer Segmentation (RFM): Identify your "Whale" customers vs. those at risk of churning.
  • Ad Spend Optimization: Analyze ROI/ROAS to see exactly where your budget is being wasted.
  • Multi-Channel Attribution: Understand which touchpoints actually lead to a sale.
  • Predictive Modeling: Use Python to forecast sales or customer lifetime value (CLV).
  • Interactive Dashboards: Professional Excel or Looker Studio reports that make sense at a glance.

My Technical Stack:

  • Python: Pandas, NumPy, Matplotlib, Seaborn (for deep statistical analysis).
