Cristian Barbosa Chombo
I run Windows Server, Linux, VMware, Hyper‑V, and Citrix environments, along with backups, user accounts, and the documentation that goes with them.
Profile
I've been working in IT since 2017, starting on the help desk and working my way up to servers and the cloud.
I manage endpoints, servers, cloud tools, backups, identity workflows, and user support across Apple, Windows, Linux, VMware, AWS, healthcare, education, and multi-site environments.
I write things down, fix problems at the root, and stay calm when something breaks.
