Infrastructure Engineer with expertise in DevOps and cloud solutions.
What I'm looking for
As an Infrastructure Engineer at Opn, I have successfully set up and configured API-Gateway in Terraform for a network-token project, ensuring scalability and authorization requirements are met. My collaboration with the development team on the Xero-integration project has further honed my skills in designing and configuring complex systems. I have also executed critical upgrades to EKS and Istio, demonstrating my commitment to maintaining high service availability through prompt issue resolution during on-call rotations.
Previously, as a DevOps Engineer at Perceptra, I migrated the entire AWS cloud system to Infrastructure as Code (IaC) using Terraform and built a CI pipeline in GitLab. My efforts in automating scaling solutions for deep-learning services not only improved scalability but also significantly reduced cloud costs. My experience at GovTech as an Associate DevOps Engineer allowed me to achieve remarkable cost savings and streamline processes through innovative solutions like Terraforming functionbeat and automating tenant onboarding with a Kubernetes operator.
