I'm a full-stack developer with about five years of experience. Most of what I build runs in public spaces: the screens and audio systems that people rely on in metro stations and airports.

My engineering approach is grounded in object-oriented design, SOLID and clean code, with design patterns applied where they solve a real problem. I structure applications with MVC on web projects and MVVM on mobile, and automated tests are part of the workflow. It is increasingly shaped by agentic AI workflows with Claude Code.

I hold a B.Sc. in Computer Science from PUC Minas and a technical diploma in IT from IFSULDEMINAS. At Sillis I build passenger information applications for São Paulo Metro Line 17 and Guarulhos Airport. I design RESTful APIs, consume data from other services and use it to drive what each application does. Before that, at BMS Tecnologia, I built energy contract management for factories with Laravel on AWS, gathering requirements directly with the client.
