Rockstar🎓
Top SchoolGeorge Yermulnik is a Lead Software Engineer and seasoned DevOps/Infra specialist with over two decades of UNIX systems administration experience and 11 years focused on cloud infrastructure, primarily AWS. He leads and mentors squads designing secure, compliant multi-account AWS landing zones and automates complex IaaC workflows using Terraform, Packer, Ansible, Jenkins and Azure DevOps. George has built resilient production services—Vault clusters, custom AMI bakeries, Egress-filtering systems and cross-account networking—often under tight migration timelines and strict governance frameworks.

Comfortable partnering with AWS Professional Services and security teams, he brings a pragmatic focus on policy-as-code, tagging/enforcement and operational reliability. An attention to detail and long history in DNS, mail and hosting infrastructure complement his cloud-native leadership, making him adept at bridging legacy systems and modern IaC practices.
