Hello, I'm a Brazilian full-stack developer!
João Marinho
Full-stack developer and researcher
About me
I am a full-stack developer and Computer Science student at UFF, based in Niterói, Brazil. I enjoy turning complex, real-world problems into reliable and user-centered products, especially at the intersection of software engineering, Data Science, and Human-Computer Interaction. My experience spans product delivery, research, cloud infrastructure, data-intensive systems, and open-source projects.
Tech Stack
I build full-stack and data-driven systems with TypeScript, Python, React, Next.js, Node.js, Spring Boot, PostgreSQL, and Redis. I am particularly interested in Data Science and Human-Computer Interaction: using data to understand complex systems and designing interfaces that make those insights clear, useful, and accessible.
