About me

I'm a Software Engineering student at FIAP who builds production-ready systems and developer tools. Most of my work is full-stack, with Node.js and TypeScript at the core.

Alongside my studies, I run SympleCRM, my own CRM SaaS, so I handle the whole product myself, from writing the code and deploying it to supporting the customers who use it.

I'm also deep into AI and automation, using tools like n8n to build smarter workflows and ship more complete products.
