👋 About me

Data Science undergraduate student at Universidad Internacional de La Rioja (UNIR), currently working as an AI QA Engineer Intern at ObviousFuture — a company specialising in secure, private, on-premise AI systems for enterprise clients.

My background is in Sports Science research (UFSC, Brazil), where statistical analysis and evidence-based decision-making were central to my work. I'm transitioning that analytical rigor into Data Science and AI quality assurance.

🔍 Open to junior opportunities in Data Analysis, Data Science, or AI/ML QA in Spain.
