    DevOps Engineer

    2024 -

    Modoyo is a small gaming company. Marcus engineered the end-to-end AWS platform for an online game, focusing on secure, scalable, and automated foundations. He combined platform engineering with security operations to harden services, standardize deployments, and enable fast, safe delivery for backend and game server workloads.

    Design, secure, and operate AWS infrastructure with strong guardrails and IaC/CI/CD; manage game server operations and developer workflows.

    Implement AWS IaC with Terraform, enforcing least-privilege IAM, KMS encryption, VPC segmentation, tagging, and policy controls.
    Build CI/CD with GitHub Actions/CodeBuild/CodePipeline, adding quality gates, image scanning (ECR), and automated validations.
    Manage ASG-based game servers with CloudWatch metrics and alarms; instrument EKS services with Prometheus and dashboards in Grafana.
    Operate and maintain ASG-based game servers in AWS, with metrics and alarms in CloudWatch.
    Set up and manage EKS for backend services, with observability being Prometheus scraping with Grafana dashboards.
    Provision and harden EKS for backend services (matchmaking, scaling, telemetry), applying RBAC, network policies, secrets management, and audit logging. - Automate Docker ArgoCD deployments so backend repos continuously deliver to EKS.
    Manage secrets and configuration with Secrets Manager and Parameter Store; standardize operations via SSM.
    Integrate identity and access for player/admin flows with Cognito; improve resilience with Route 53, CloudFront, and Global Accelerator.

    Result: Delivered a hardened, reproducible AWS platform with built-in security controls and automated deployments. Release friction decreased, scalability and reliability improved for game servers and backend services, and operational risk was reduced through encryption, least-privilege access, image scanning, and continuous monitoring.
