About Andrea

Data Scientist 📊🧑🏻‍🔬 with a PhD in Mathematics 🎓🧮🇸🇪 and 3+ years of experience across data science, analytics, and data engineering. I design and deploy scalable data pipelines and cloud-native analytics solutions that turn complex data into actionable insight.

At Open Cosmos 🛰️🇪🇸 I’ve built geospatial data workflows on Google Cloud to support environmental and air-quality monitoring, while at Prima Assicurazioni 🚗🇮🇹 I developed ML and NLP-driven models improving risk prediction and fraud detection efficiency.
My research background 🔬 trained me to tackle problems analytically and think systemically, skills I now apply to real-world data challenges.

I’m passionate about leveraging AI✨ and automation🤖 to make data products smarter, faster, and more reliable.
