01.About
I'm a Computer Science student at the Institute of Computing of UFAL (Federal University of Alagoas), in Maceió, Brazil. I like understanding how things work under the hood and turning what I learn in class into projects that actually run and that I can show.
My interests revolve around algorithms and competitive programming, training with ICPC problems; computer graphics, which I'm currently studying with Godot; and AI, especially applications built on language models, like the Discord bot I made with Gemini.
Here I gather the projects I like the most, with the context of each one and what I learned along the way.

This project conducts an in-depth exploratory data analysis (EDA) of the Delhi Air Quality dataset using R Markdown. The analysis explores pollutant levels, temporal trends, and correlations between environmental factors, while integrating code, visualizations, and narrative in a single reproducible document.
