Market Eye • Período integral

Jan 2022 - Jan 2025 • 3 yrs

As a Senior Data Analyst at MarketEYE, I was responsible for designing and implementing end-to-end data analytics solutions to support marketing intelligence, sales optimization, and strategic decision-making. I worked extensively with structured and semi-structured datasets, ensuring data quality through advanced cleaning, transformation, and validation processes using SQL, Python, and Excel. My role involved building and maintaining relational databases, writing optimized SQL queries for data extraction, and creating automated reporting pipelines to reduce manual workload and improve reporting efficiency. I developed interactive Power BI dashboards with advanced DAX measures, calculated KPIs, and dynamic drill-through capabilities to monitor campaign performance, customer acquisition metrics, revenue trends, and sales funnel analytics. I conducted detailed market research and statistical analysis to identify customer segmentation patterns, behavioral trends, and competitive positioning insights. Using data modeling techniques, I structured datasets to enable scalable reporting and improved query performance. I collaborated closely with marketing and sales teams to evaluate campaign ROI, conversion rates, and customer lifetime value (CLV), helping refine targeting strategies and budget allocation. Additionally, I prepared executive-level analytical presentations, translating complex quantitative findings into clear, data-driven business recommendations. My work directly supported marketing strategy optimization, performance forecasting, and operational efficiency improvements. Throughout my tenure, I strengthened my expertise in data modeling, KPI framework development, performance analytics, and business intelligence architecture. I consistently ensured that analytical outputs were not only technically robust but also aligned with organizational objectives and measurable business outcomes.
