Full Stack by Day, Root User by Night

Profile Picture

I'm Mateus Felipe — full-stack developer and Linux-powered human.

I build across the stack with React, Next.js, Node.js, Nest.js, and dive into DevOps when the code needs to meet the cloud.

At BrSuper Internet, I'm the creator and primary maintainer of BrTools, a multi-tool platform that powers BrSuper Internet's ISP operations. Beyond that, I also develop freelance projects, crafting solutions that mix frontend, backend, and infrastructure with the same energy and care.

My toolbox lives in the TypeScript stack, but I'm also exploring the sharp edges of Rust and the solid grounds of Java.

I've been riding Linux for ~10 years, chasing knowledge in security, system hardening, and the occasional rabbit hole into obscure commands.

When I learn something new, I share it, through blog posts, configs, and experiments that sometimes spiral into the rabbit hole.
