Aws Freelancer Required to manage servers from time to time

I am looking for an experienced freelancer to help me manage my servers on a semi-regular basis. This role requires regular maintenance, such as performing software updates and keeping backups. Additionally, the freelancer must have the skills to do some simple troubleshooting, as well as make configurations changes as needed. Familiarity with Amazon Web Services is a must, and I would need the freelancer to be available on call at times. This is an ongoing role and I'm looking forward to your help. Thanks in advance!
