Data Analyst
I’m a Data Analyst with a background in Telecommunications Engineering and experience transforming data into clear insights that support better business decisions.
My main focus is data analysis, visualization, and business intelligence, using tools such as Power BI, SQL, Python, Excel, and Pandas to clean, analyze, and visualize data. I enjoy turning complex datasets into intuitive dashboards and actionable insights that help teams understand performance, identify opportunities, and solve problems.
I also have experience in project and process management, working with cross-functional teams, monitoring KPIs, managing requirements, and supporting continuous improvement initiatives. This combination allows me to approach data not only from a technical perspective, but also from a business and project-oriented mindset.
I’m constantly learning and looking for new challenges where I can combine data, technology, and business understanding to create solutions that generate real impact.
