With the urgency of your project in mind, I'd like to offer my 9 years of extensive experience in Linux and Cloud server management where managing, migrating, and optimizing DNS settings within GoDaddy and Namecheap is second nature to me. The kind of work that you require — updating A Records and CNAME Records — aligns perfectly with my expertise; I assure you a quick and efficient transition.
Moreover, I have always been entrusted with managing critical cloud infrastructures on platforms like AWS, Gcloud, Digitalocean. My vast experience also includes building Docker images, using Ansible and Terraform for deployments, deploying and configuring Elastic search ELK for log analysis, among others.
Apart from my domain-specific skills, I also bring exceptional troubleshooting capabilities for any network issues that might arise. This includes dealing with TCP/IP, LAN/WAN networking, DNS, DHCP issues. Being well acquainted with cloud platforms, as well as network management technologies like VMware makes me an attractive candidate for handling this task seamlessly and promptly.
