Professional summary

I am an IT professional with over 16 years of experience working in highly complex corporate environments, both national and multinational. My expertise lies in connecting technology with business strategy to drive impactful results. I specialize in Cloud Computing, particularly Oracle OCI, Docker containerization on Linux, and Microsoft 365 administration.

Throughout my career, I have designed and implemented advanced FinOps solutions focused on cost optimization within Oracle Cloud environments. I have developed AI-driven cost monitoring systems that provide real-time tracking of expenditures by large language models, tokens, and inference costs.

I have hands-on experience orchestrating multi-agent AI pipelines using n8n, managing containerized infrastructures, and administering platforms such as OpenWebUI. My technical skills extend to managing Microsoft 365, Exchange Online, OpenVPN, Zabbix, and Grafana, ensuring seamless operations and security.

I am passionate about translating complex technical metrics into business language, enabling stakeholders to make informed decisions. My approach combines governance frameworks, automation, and security best practices to optimize cloud environments and reduce waste.

Currently, I serve as a Cloud Administrator at VITAI, where I lead FinOps initiatives and AI cost monitoring projects. I have successfully implemented cost governance frameworks, automated anomaly detection, and optimized cloud resource usage. Prior to this, I held roles in support and system administration, managing identity security, network infrastructure, and enterprise-scale access management.

I continuously pursue professional development, holding certifications in Oracle Cloud, Google Cloud, CompTIA Cloud+, Microsoft Azure, VMware, ITIL, and Agile Scrum. I am committed to leveraging my skills to drive innovation and efficiency in cloud operations and FinOps practices.
