Hi, I'm Camila Lightfoot

  • πŸ’Ό LinkedIn:

Camila Lightfoot

I'm a Computer Science student at George Mason University and an AI Fellow at Break Through Tech in partnership. I’m passionate about applying Machine Learning to real-world problems, from sentiment analysis to image classification, with a strong foundation in Python, scikit-learn, and data-driven storytelling. I love exploring how data can tell stories and drive impactful decisions. My work spans from building classification models to preparing complex datasets for predictive modeling β€” always with an eye toward clarity, reproducibility, and practical application.

✨ Fun Fact

I’m from Colombia πŸ‡¨πŸ‡΄ and I love drinking hot chocolate with cheese!
It might sound unusual, but trust me β€” it’s delicious, especially with queso campesino or string cheese.
