Aspiring junior data analyst transitioning into data science and engineering, delivering clean models and clear visual insights.
ArgentinaWhat I'm looking for
I’m a professional in transition into Data Analysis, Data Science and Data Engineering, trained in SQL, Python, and Power BI. I bring a strong background in education and administrative management, with strong organizational skills, analytical thinking, and clear communication.
From my Teaching Assistant and lead classroom teacher experience, I learned to plan, monitor progress indicators, analyze qualitative and quantitative information, and prepare reports that support better decisions. Through CS50 and CS50s, plus the Coderhouse Data Science Career Track, I’ve built practical skills in data cleaning, transformation, visualization, exploratory/descriptive analytics, predictive modeling, and applied NLP, and I’m now seeking a junior position focused on data cleaning, modeling, and visualization.
