Marcello Sampaio

I’m studying Software Engineering at Centro Universitário Santo Agostinho (UNIFSA) and seeking a software development internship. My hands-on work includes full-stack development and data analysis through personal projects and undergraduate research.

For NutriAI, a research project at Centro Universitário Santo Agostinho (UNIFSA), I participated in requirements gathering and system architecture modeling. I also prototyped high-fidelity interfaces in Figma, applying usability, accessibility, Design Thinking, and LGPD considerations.

I developed ML Heroes, a full-stack web system with role-based authentication, encrypted passwords, and CRUD features for heroes and abilities. It uses PostgreSQL through Supabase and is deployed on Railway.

In my State of Data Brasil 2024–2025 project, I analyzed survey data to identify factors influencing data professionals’ salaries in Brazil, applying Spearman correlation and data standardization. I published an interactive dashboard in Google Looker Studio, and also developed a Java sales system for product registration, sales management, and inventory control.
