VietnamWhat I'm looking for
I am an IT specialist and systems administrator with over a decade of hands-on experience supporting Windows, Mac and virtualized environments, administering cloud-native platforms (Kubernetes, Docker, VMware) and ensuring compliance with ISO 27001/9001 and ITIL practices. I consistently deliver stable, secure IT operations for hundreds of users, optimize infrastructure, manage network/security devices, and lead vendor coordination to meet SLAs and reduce costs.
My career highlights include administering large corporate estates, deploying monitoring (SolarWinds, PRTG, Splunk), driving cloud and virtualization initiatives, and implementing MDM and Office365/Active Directory solutions. I am results-oriented, security-minded, collaborative, and aiming to transition into an IT Manager role to improve operational efficiency and security at scale.
