// about

I deliver cloud and DevOps solutions that generate measurable business impact in mission-critical financial environments. As a DevOps and Cloud Engineer at Banco Itaú Unibanco, I operate where reliability, scalability, security, and compliance are non-negotiable.

My work spans cloud architecture, CI/CD automation, platform engineering, and observability — combining deep technical execution with a strong focus on real business outcomes.

I hold a Bachelor's degree in Computer Science from UFRPE and co-authored a research paper on ISO 27005 presented at the Brazilian Computer Society Congress.
