Message

At FOCUS AUTOMAÇÃO DE SISTEMAS (iFOCUS), I develop the React and TypeScript frontend of a multi-tenant ERP, including a project management module, and work alongside the team on its NestJS backend using Domain-Driven Design.

I also designed, prototyped and developed SmartCIP interfaces for Zebra TC22 devices, replacing paper-based CIP cleaning records. I tested the system with production teams on the factory floor to validate its usability in the operating environment.

For Cimed, I prototyped an industrial monitoring platform in Figma. I’ve also built responsive client and e-book websites, and deploy applications with Docker and Prisma on Linux servers.
