About Aleix

As a seasoned System Administrator with nearly a decade of experience, I specialize in managing IT infrastructure, virtualization, and storage solutions across Windows and Linux environments. My expertise includes overseeing server clusters, optimizing system performance, and automating processes through scripting, particularly with PowerShell, to ensure seamless operations and reduce downtime.

I have a strong background in administering virtualized environments, using platforms like Hyper-V, VMWare, and Proxmox, and managing essential network components such as firewalls, backups, and security systems. Additionally, I have implemented and maintained critical infrastructure tools, including monitoring and inventory management systems, to enhance visibility and control.

Collaboration is key in my approach, working closely with cross-functional teams to design and execute infrastructure improvements, from server migrations to cloud integration. I am continuously advancing my knowledge, currently focusing on cloud technologies, particularly in Microsoft Azure, to stay ahead in an evolving IT landscape.
