At Telefonica Brasil (Vivo), I build and review Python automations that consolidate weekly vulnerability and cloud security-misconfiguration reporting across workstreams. I analyze Critical and High CVEs, track remediation, patches and hardening actions, and preserve traceability to source files.

I use Tenable.sc, Tenable.io, Prisma Cloud, Azure and Jira to validate controls, document evidence, and coordinate follow-up with technical teams and stakeholders. After an accelerated handover, I temporarily owned Cloud Security routines, leading meetings, deliverables and indicator presentations.

I'm also contributing to Omnia, an inclusive education platform, through its public React, TypeScript and Vite frontend, with reusable components and accessibility-focused interfaces.

My earlier work in credit and administration strengthened my approach to documentation, data validation, risk review, process standardization and knowledge transfer. I'm interested in Ubuntu engineering, open-source software, systems reliability and secure automation.
