About Me
With over 20 years of hands-on IT experience, combining strategic leadership with technical execution. Bachelor of Electrical Engineering (Facens) and Systems Analyst (Estácio). At HP, as Server Automation Architect, I sustained a global data center of 160,000 servers: core, satellite, and agent, with parallel Shell patching. At VA Engenharia I led hybrid cloud (AWS, Azure, GCP), FinOps, and local generative AI.
