I am a versatile individual with experience in various fields, including data collection, transformation, and organization for data-driven decision-making. I possess a comprehensive understanding and proficiency in platforms and tools such as SQL, spreadsheets, Tableau (Desktop, Server, Prep Builder), Power BI, R, Python, and Alteryx for effective data analysis and visualization. With strong communication, organizational, and analytical skills, I have gained several years of experience in documentation, evaluation, and analysis by working in different fields.
As a historian I researched Military History, working together with military institutions and universities. At the same time, I taught High School students for a few years before coming to Germany. Here I transitioned to an Educator at an Elementary School where I worked for several years, further developing my skills in observation, documentation, and analysis, but also communication, which are crucial for creating activities that aid in children's growth and development.
In 2022, I pivoted towards Data Analytics and Visualization after getting to know the field and immediately realizing what I wanted to work with in the future. Surprisingly, the skills required in both historical research and data viz are quite similar, as the methodology of historians resembles the phases of data analysis exceptionally well. I am passionate about telling the story behind the data.
