IT Infrastructure Engineer with 10 years of experience leading operational continuity and technology modernization of critical architectures. My focus has evolved from technical support and telecommunications to designing cutting-edge solutions in Cloud, Virtualization, and Automation.
Throughout my career, I have evolved from managing traditional systems to orchestrating modern ecosystems based on Infrastructure as Code (IaC). My priority is eliminating human error and optimizing costs through container implementation, CI/CD pipelines, and advanced automation. I don't just manage servers; I design resilient architectures that ensure infrastructure is a growth engine for the business and not a bottleneck.
As a technical reference, I have a strong execution capability in high-pressure environments and adverse situations. My differentiator is the ability to translate strategic objectives into executable technical topologies (AWS, hybrid environments, Proxmox), always ensuring high availability and information security. I am a professional open to change, focused on disruptive actions that promote operational efficiency and the organization's technological development.
With this training, I prepare to lead projects in technologically interconnected environments, combining management skills with advanced technical knowledge. The program allows me to develop capabilities to lead multidisciplinary teams, implement emerging technologies, and make strategic data-driven decisions for digital transformation of organizations.

Senior IT Infrastructure Engineer — designing resilient architectures
Hybrid Cloud & On-Premise infrastructure, IaaS, virtualization, and automation for mission-critical operations
Managed and executed the comprehensive recovery from a massive service outage caused by a loss of redundancy in local servers. Organized the technical response to stabilize and restore the infrastructure, returning full operability to the business.
Successful operational recovery of critical services. Handling the crisis provided documented technical evidence of the server degradation, justifying the imminent shift toward a modern, resilient architecture.
Replacement of obsolete services with secure containerized architectures. Migrated legacy SMTP Relay on Windows Server 2022 to Docker containers running Postfix, resolving IIS 6 dependencies and integrating secure connectors to MS 365.
Service isolation, improved stability, strict IP control, and complete elimination of legacy technical debt. Resulting in a modern, maintainable, and production-ready architecture.
I deploy critical infrastructure for high-volume support operations. I configure and stabilize IP plants, SIP trunks, and E1 links secured via global VPN tunnels, ensuring uninterrupted enterprise communications.
Comprehensive implementation of VoIP solutions for high-transactional demand environments. Traffic security via corporate firewalls and IPSec VPN tunnels, maintaining critical business operability.
Resolved critical hardware and software obsolescence by replacing unmanaged legacy proxies with Next-Generation Sophos Firewalls (NGFW). Designed and implemented strict policies, application control, and proper network segmentation.
Elimination of security breaches and total control over outbound internet traffic. Reduced latency, structural network organization, and the establishment of a secure baseline for business growth.
