Fabian Pertuz

I am a Data Analyst specialized in Marketing and Customer Insights, focused on helping businesses improve conversion rates, optimize marketing performance, and make data-driven decisions that increase revenue.

I work with tools like SQL, Python (Pandas, NumPy), and BI platforms such as Tableau and Power BI to transform raw data into clear, actionable insights. My experience includes analyzing key business metrics such as CAC, LTV, conversion rates, and ROI to identify growth opportunities and improve profitability.

I have hands-on experience performing exploratory data analysis (EDA), building automated data workflows, and creating dashboards that help stakeholders monitor performance and make better decisions. I also apply statistical analysis and A/B testing methodologies to validate hypotheses and ensure decisions are backed by reliable data.

One of my strengths is combining technical analysis with business understanding. I have worked on projects involving marketing performance optimization, customer segmentation, revenue analysis, and demand forecasting. This allows me not only to analyze data, but also to translate it into strategies that drive measurable results.

Additionally, I have experience working with modern data tools such as AWS (S3, Athena, Glue), Databricks, Snowflake, and PySpark, which allows me to handle and process large datasets efficiently.

Before transitioning fully into data, I worked in marketing and operations, which gave me a strong understanding of how businesses acquire customers, manage pipelines, and optimize processes. This background helps me align data analysis with real business needs.

I am proactive, detail-oriented, and focused on delivering practical solutions. Whether you need to analyze your marketing performance, build dashboards, clean and structure your data, or identify growth opportunities, I can help you turn your data into meaningful results.
