I’m a Full Stack Developer Intern at John Deere’s Intelligent Solutions Group, where I work on full stack solutions with Node.js and TypeScript.

As an Undergraduate Research Fellow at Instituto Federal de São Paulo (IFSP) - Campus Salto, I conceived, developed, and published Kaelum.js, an open-source Node.js framework with 600+ monthly downloads that cuts Express boilerplate by 50%+. I also built Kargo, a Java and Spring Boot REST API for e-commerce inventory management.
