Leonardo Barbosa

IT Infrastructure & Systems Engineer | Cloud & DevOps Enthusiast With 9+ years of hands-on experience, I design and manage secure, scalable, and high-availability IT environments, from on-premises datacenters to cloud and containerized infrastructures. My work spans the full infrastructure stack: Linux and Windows Server administration, Docker and Kubernetes, VMware virtualization, cloud platforms (Azure, AWS, Oracle Cloud), and network security with Fortinet and Sophos. I also work with monitoring tools like Zabbix, Grafana, and Prometheus to keep systems observable and reliable. Beyond infrastructure, I have a development background in Python, Java, and JavaScript, and hands-on experience with SQL and data analysis, which helps me bridge the gap between systems engineering and software. Throughout my career I have had the opportunity to work across diverse and demanding environments. At Conservas Oderich, I supported industrial production systems, implemented network monitoring solutions, administered Totvs ERP with Bloco K compliance tools, and contributed to the digitization of production processes. At Valmet, a global leader in industrial automation and services, I took on broader responsibilities, leading local IT operations across multiple units in Brazil, managing datacenter infrastructure, overseeing VMware and Veeam Backup environments, and coordinating the IT integration process following Valmet's acquisition of Demuth. One of my most significant projects was leading the migration of Oracle databases to Oracle Cloud, ensuring business continuity throughout the transition. I value clear communication, collaborative problem-solving, and simple but effective solutions to complex challenges. I am always looking to grow, whether by deepening my technical expertise or by taking on projects that push me outside my comfort zone.
