Data Analyst & Digital Insights Assistant @ Moce Desenhos

About

Data Analyst focused on one thing: turning data into better decisions. I work with SQL and Advanced Excel to analyze business, operational, and digital data, identify trends, and generate insights that improve performance and support strategy. At Metro Menlyn, I analyzed sales and inventory data, helping to identify demand patterns and support operational decisions. At Moce Desenhos, I worked with digital performance and customer data across multiple companies, extracting insights that contributed to business growth and improved online visibility. I specialize in data cleaning, data transformation, dashboard development, and analytical reporting, with a strong ability to work with structured datasets and relational databases. With a background in IT, I bring strong problem-solving skills, attention to detail, and adaptability to data-driven environments. I am focused on growing as a Data Analyst and contributing to organizations that value data-driven decision-making.
