Turning messy data into decisions that matter. Python, ML, NLP — and always learning in public.

About Me

I'm a Data Scientist focused on building things that matter. My work lives at the intersection of machine learning, NLP, and real-world impact — from helping low-literacy job seekers build resumes via WhatsApp voice messages to detecting fake news with 95%+ accuracy.

I'm also part of TAIL (Technology and Artificial Intelligence League) — the largest academic AI league in Northern/Northeastern Brazil — where I develop projects and research in AI.
