Skilled DevOps, MLOps and AWS Engineer to work! I’m a Senior AWS DevOps and MLOps Engineer with 10+ years of hands-on experience running production infrastructure, Kubernetes platforms, CI/CD systems and Linux environments. On Upwork, I’ve completed 8,900+ hours and earned $200K+, including long-term AWS cloud /Linux infrastructure work and projects involving AWS services , EKS, ECS migrations, CloudFormation, VPN connectivity, Docker and deployment automation. My core work is around AWS, EKS/Kubernetes, Terraform, CI/CD, observability, production troubleshooting and infrastructure reliability. I usually help teams with: 1. AWS infrastructure design, migration and production support 2. EKS and Kubernetes deployments, scaling and troubleshooting 3. Terraform and CloudFormation infrastructure automation 4. Docker, ECS, Fargate, ECR and container deployments 5. GitHub Actions, Jenkins and GitLab CI/CD pipelines 6. Helm, ArgoCD and GitOps workflows 7. AWS networking, IAM, VPC, ALB/NLB, Route 53, RDS and S3 8. Prometheus, Grafana, CloudWatch, logging and alerting 9. Production incident investigation and root-cause analysis 10. Infrastructure cost optimization, backup and recovery planning I have worked across fintech, healthcare, media and education environments, where reliability, security and controlled production changes are important. MLOps and AI infrastructure I also work on deploying and operating AI/ML workloads. This includes Dockerized ML services, Kubernetes-based model deployments, GPU-backed workloads, persistent storage, API routing, autoscaling, monitoring and production support. For heavier AI workloads, I pay particular attention to GPU utilization, memory, queue depth, model loading time, worker concurrency and cost rather than scaling only on CPU. AIOps and AI-assisted operations I build practical AI-assisted workflows that use real infrastructure data such as logs, metrics, Kubernetes events and runbooks to speed up troubleshooting. Examples include: 1. CloudWatch log and trace analysis 2. Kubernetes failure investigation 3. CI/CD pipeline failure analysis 4. ArgoCD deployment and rollout checks 5. Alert and incident summarization 6. AWS infrastructure and security audits I use AI as an investigation and automation tool, not as an uncontrolled production operator. Changes to production remain reviewable and reversible. My approach is simple: understand the existing environment first, identify the real bottleneck or risk, make the smallest safe change, verify it through monitoring, and document what was done. If you need help with AWS, Kubernetes, CI/CD, production troubleshooting, MLOps or infrastructure automation, I’m comfortable taking ownership from investigation through implementation and verification.
