Ravinder K.

Staff / Principal-level DevOps & DevSecOps engineer with 12+ years running production cloud platforms - I keep systems up (99.99% uptime), ship faster (20% faster deployments) and make them secure, observable and cost-efficient. Career highlights: Staff Software Engineer at Tekion (migrated production services from EC2 to Kubernetes with Karpenter + KEDA autoscaling), Principal DevOps at VerSe Innovation (Dailyhunt/Josh), DevOps Manager at Times Internet. Today I run AWS infrastructure for a PCI-compliant travel-tech platform. On Upwork, you work with me directly - I do the hands-on work myself. WHAT I CAN DO FOR YOU - EC2/VM to Kubernetes migrations: containerize services, move them to Amazon EKS with minimal downtime, and cut over safely - Kubernetes autoscaling & cost: Karpenter (Spot + on-demand node provisioning) and KEDA (event-driven pod scaling from SQS, Kafka, Prometheus, cron) - AWS infrastructure as code: EKS/ECS, VPC, IAM, ALB, RDS/Aurora, Lambda, API Gateway - with Terraform, CDK, CloudFormation - Observability & AIOps: Prometheus, Thanos, Grafana, ELK, CloudWatch - dashboards, SLO-based alerts, anomaly detection and automated remediation - DevSecOps & cloud security: IAM least-privilege audits, AWS WAF, GuardDuty, security incident response, PCI-scoped environments - CI/CD: Jenkins pipeline-as-code, Docker, Helm, container-based pipelines and safe rollouts - MLOps infrastructure: Kubernetes-based platforms for deploying and monitoring ML/AI services - Cost optimization: Savings Plans, rightsizing, Spot strategy, weekly cost reporting - Email infrastructure: Amazon SES, SPF/DKIM/DMARC, deliverability fixes TYPICAL ENGAGEMENTS - Migrate an EC2-based app to EKS with Karpenter/KEDA autoscaling - Set up monitoring and alerting for an AWS/Kubernetes stack - Security review of an AWS account with a prioritized fix list - Build or fix CI/CD pipelines and Terraform code - Cut your AWS bill without hurting reliability - Ongoing part-time DevOps support HOW I WORK Clear written plans before changes, testing in non-prod first, runbooks and documentation at handover, and plain-language explanations so you always know what was done and why.
