Hi, I’m Fiorella 👋

Data Scientist | Python · SQL · Machine Learning · Analytics

I’m a Data Scientist interested in turning complex data into clear insights and practical solutions. My hands-on training includes data analysis, statistical methods, machine learning, time series, and predictive modeling, applied to a variety of real-world business problems.

My background is non-traditional and international, spanning teaching, hospitality, and multilingual work. These experiences have strengthened my adaptability, attention to detail, problem-solving skills, and ability to explain complex ideas clearly to people from different professional and cultural backgrounds.

I enjoy working through messy problems, asking questions, finding patterns, testing ideas, and turning analysis into recommendations that support better decisions. I’m particularly interested in opportunities where data can be used to improve processes, understand behavior, anticipate outcomes, and contribute to meaningful challenges across different industries.

When I’m not working with data, you’ll probably find me marathon-reading romance or fantasy books, teaching English, or spending time outdoors. 🌿
