As a DevOps lead, spearheaded the creation of a secure, high-performance platform compliant with PCI DSS standards. Provided mentorship in DevOps methodologies and orchestrated scalable environments with custom CI/CD automation. Utilized a tech stack including GitLab, Kubernetes, Terraform, and various AWS services.Highlights / Outcomes:• Led a team of DevOps professionals to create the platform and infrastructure from scratch. This involved discussions with the Head of Security and Engineering Lead to establish a production-grade environment that strikes a balance between security (PCI DSS compliance), performance, cost-effectiveness, reliability, and integrity.• Provided mentorship in DevOps methodologies, emphasizing adherence to DevSecOps/GitOps/DevOps best practices.• The environments are designed to be highly scalable and reliable, with auto-scaling configured. Custom CI/CD automation is implemented to enhance user permission control and reduce deployment time, thereby requiring fewer permissions in certain environments.• The tech stack encompasses GitLab, Kubernetes, Terraform, Helm, ArgoCD, OpenSearch, X-Ray, OpenTelemetry, Grafana, Prometheus, AWS SSO, Cognito, Aurora PostgreSQL, EKS, Lambda, ECR, WAF, Secret Manager, and Snyk.

At IAG Innovation Labs, I collaborated with cross-functional teams spanning SG and AU to challenge existing touchpoints, redefine journeys, and innovate insurtech products that embody IAG's purpose through human-centered practices.Highlights / Outcomes:• Led cross-functional teams across SG & AU to develop multiple innovative insurtech products.• Established a secure environment from development to production levels.• Implemented CI/CD pipelines to ensure smooth and secure deployments across all environments.• Implemented and enforced services/user policies to manage access permissions effectively.• Ensured the implementation and configuration of site reliability tools for enhanced system stability.

As an Engineer in the M-Daq DevOps Team, I played a crucial role in managing our cloud infrastructure across both AWS and GCP platforms to support our cross-function internal teams. While I had a broad focus, my primary responsibility was maintaining the AWS Cloud Infrastructure to ensure reliability and compliance with the AWS Well-Architected Framework and MAS Framework for security.Highlights / outcomes: • Peer review work to ensure implementation complies with MAS and AWS Well-Architected Framework• Enhancing our security measures with TrendMicro Deep Security and Cloud Conformity tools• Actively participated in planning and upgrading our infrastructure, including Terraform versions 0.11 through 0.15• Creating and refining Terraform Modules for both AWS and GCP resources• Architect, plan & deploy automation with AWS services stack (e.g API Gateway, SNS, SQS, Lambda) to maintain the balance in terms of budget, security & performance via IaC tool Terraform• Managed and improved CI/CD pipelines using Jenkins/GitlabCI runners within Kubernetes for deploying cloud resources• Containerization technologies such as Docker, Kubernetes, and Helm, where I've leveraged these tools to streamline our deployment processes• Experience in Log management such as ELK Stack and Cloudwatch• Experience in Matrix management such as Prometheus, Grafana & Cloudwatch• Collaborating closely with the SRE Team to progressively refine log or matrix monitoring to reduce numbers of false positive alerts/triggers• Led in Involvement of designing and implementing an agentless architecture using Ansible AWX (Red Hat Ansible Tower) to manage cloud/on-premise instances efficiently• Design, Implement & managed a hybrid cloud infrastructure between on-premise and cloud infra• Actively suggested, created, and deployed best practices to optimize infrastructure efficiency and reliability, contributing to the overall success of our team's efforts.
