What I'm looking for

I'm looking to build secure full-stack or AI/ML systems where I can apply software engineering, security research, data analysis, and end-to-end product development.

I’m a Machine Learning and Data professional with a B.Sc. in Data Analysis from the University of Messina. My background combines Machine Learning, data analysis, software engineering, and cybersecurity.

What I enjoy most is taking a problem that is initially messy or unclear, figuring out what the data can actually tell us, and turning that into a working solution. My projects range from predictive modeling and feature engineering to NLP, anomaly detection and network analysis, as well as building full-stack applications around analytical workflows.

My background is a little broader than the typical data-focused path: alongside ML and data analysis, I’ve worked with backend and full-stack development and have a strong interest in cybersecurity. This helps me approach ML problems not only from the perspective of a model, but also with an understanding of how the resulting solution can work as part of a real system.

I’m currently looking for opportunities in ML Engineering, Data Science, or Software Engineering where I can work on interesting real-world problems, keep learning, and contribute beyond simply writing code.
