• SRE / Senior Linux Sysadmin / Platform Engineering

  • Aug 2017 - Apr 2021

  After one year at WorldFirst, I was promoted to a Senior Linux role. Initially maintaining the same responsibilities, we also began to shift from traditional datacentre solutions to AWS. Since 2018, we have adapted our infrastucture to deploy all applications in AWS, initially using EC2, but later EKS. We have adopted Devops mentality and tooling, using packer, ansible and terraform to build platform agnostic images and deployment tooling. We now provide frictionless paths for developers to deploy applications through pipelines to EC2 or EKS environments. Show less
