I need reliable hands-on help for day-to-day end-user issues across a mixed estate that runs Ubuntu, CentOS, Debian and the occasional Windows Server VM. Most workloads sit on private clouds built with OpenStack and CloudStack, while a growing share has moved to AWS, so you should be equally at home troubleshooting instances through the CLI, console, or API. Tickets range from user-account problems, package and kernel updates, VM lifecycle hiccups, and network/storage quirks, through to deeper cloud tasks such as quota tuning or security-group cleanup. Clear English documentation inside Freshdesk is mandatory, and you’ll connect through our VPN for any console work. If you already script fixes in Bash, Python or Ansible, or know your way around the OpenStack and CloudStack CLIs (plus the usual AWS toolkit), mention it—those skills are a welcome bonus. When you reply, please include: • your normal response window and on-call availability • tools you already use for monitoring or ticketing • a brief example of a tricky incident you resolved on OpenStack, CloudStack, OR AWS Short-listed freelancers will join me for a 15-minute screen-share of the lab so we can confirm fit and access requirements.
