About

Electrical Engineer and M.Sc. candidate in Computer Science at the Federal University of Bahia (UFBA), working across systems infrastructure, networking and cloud computing.

In academic research, I implemented and operated the Proxmox hypervisor infrastructure that supports the entire Computer Science Graduate Program, including multiple research groups and containerized applications.

I have a strong foundation in DevOps and AWS, with hands-on experience in containers (Docker, Kubernetes/RKE2), deployment automation and virtualized environment security. My master's research applies machine learning to network function orchestration and distributed systems performance analysis.

I'm proficient in English and German, with international work experience in Germany.
