About

Professional summary

I am a Cloud Infrastructure and DevSecOps professional with hands-on experience designing, deploying, securing, and operating Azure, AWS, and hybrid infrastructure environments. My work combines cloud engineering, identity governance, network security, infrastructure automation, and operational reliability.

I support public-sector and enterprise cloud environments using Microsoft Azure, Microsoft Entra ID, Microsoft 365, Terraform, and Kubernetes/AKS concepts. I focus on secure resource configuration, least-privilege access, cloud governance, monitoring, and remediation of security misconfigurations.

I have practical experience managing identity and access controls, including RBAC, MFA, Conditional Access, privileged roles, access reviews, break-glass accounts, and Active Directory integrations. I also work with cloud security services such as Microsoft Defender for Cloud, Microsoft Sentinel, Azure Policy, and Microsoft Purview.

I build and document repeatable infrastructure patterns using Infrastructure as Code and Terraform. My infrastructure experience includes virtual networks, subnets, network security groups, virtual machines, storage accounts, Key Vault baselines, DNS, WAF routing, application hosting, and cloud deployment readiness.

I have supported hybrid environments involving VMware, Nutanix, Citrix, Windows Server, Linux, Azure, and Microsoft 365. I also contribute to backup, patching, incident response, business continuity, infrastructure troubleshooting, and service availability operations.

I am committed to secure-by-design practices and continuous improvement. I create technical documentation, hardening guides, runbooks, governance artifacts, and awareness materials aligned with ISO 27001, NIST, SIM3, Microsoft Cloud Security Benchmark, and DevSecOps principles.

Career history

Infrastructure & Cloud Systems Coordinator | DevSecOps National Cybersecurity Center CSIRT-RD

I serve as Infrastructure Lead supporting the administration, security, and governance of Microsoft Azure, Microsoft Entra ID, Microsoft 365, and cloud security integrations for multiple government institutions. I manage identity controls including users, groups, RBAC, MFA, Conditional Access, privileged roles, access reviews, break-glass accounts, and least-privilege governance.

I support Azure infrastructure operations, cloud security posture reviews, tenant hardening, and remediation of configuration findings using Secure Score, Defender for Cloud, Azure Policy, and Microsoft Cloud Security Benchmark guidance. I create reusable Terraform-based deployment patterns and documentation for Azure networking, virtual machines, storage, Key Vault, tagging, and baseline configurations.

I collaborate with SOC, development, infrastructure, and institutional teams on cloud, identity, DNS, WAF, connectivity, and monitoring issues. I also contribute to DevSecOps reviews, technical documentation, runbooks, compliance artifacts, and cybersecurity awareness sessions aligned with ISO 27001, NIST, SIM3, and secure access practices.

Sysadmin IT Infrastructure | Cloud Administrator | IT Support CLARORD

I supported a cloud infrastructure project for a Citrix environment with more than 500 virtual machines, validating server provisioning, virtual machine readiness, domain joins, user access, application delivery prerequisites, and secure desktop and application availability. I administered hybrid infrastructure across VMware, Nutanix, Citrix, Azure, Active Directory, Windows Server, Linux, and Microsoft 365.

I managed Azure servers, user and group access, privileged access controls, patching, update validation, and operational infrastructure changes. I documented reusable provisioning and baseline configuration procedures and created Terraform-based examples for Azure resource groups, virtual networks, subnets, network security groups, virtual machines, storage accounts, and tagging standards.

I supported Kubernetes and container hosting readiness reviews, backup and recovery operations with Veeam Backup, update management with WSUS, CyberArk-supported privileged access practices, system health checks, troubleshooting, incident response support, and operational continuity activities.

Cybersecurity Intern Secretariat of the Inter-American Committee against Terrorism - OAS

I investigated CSIRT operations and cybersecurity services delivered through the CSIRT Americas network. I researched incident management processes and maturity practices based on NIST, SANS, FIRST, and SIM3.

I supported CSIRT maturity evaluation activities under a SIM3-certified auditor by reviewing interviews, documentation, operational processes, and supporting evidence. I analyzed account lifecycle controls, privileged access processes, and incident response procedures related to identity risks and access abuse.

I developed structured findings and recommendations to improve access governance, monitoring, incident handling, and overall CSIRT maturity.

Technical Assistant | Cloud, DevOps Planeta Web Services

I supported AWS and Microsoft Azure environments, including cloud instance deployment, access configuration, secure credential practices, and technical documentation. I also managed developer provisioning, group-based permissions, secure authentication policies, and access segmentation across cloud and collaboration platforms.

I supported DevOps automation, CI/CD integrations, version-controlled deployments, QA activities, and environment provisioning. I documented repeatable cloud deployment patterns, environment variables, access prerequisites, and deployment steps for development and QA environments.

I gained practical exposure to Docker and Kubernetes deployment concepts and coordinated team tasks as an acting Scrum Master. I also supported occasional development activities using C#, Java, and MySQL.
