DevSecOps Engineer at Teaching Strategies

Architected and operated enterprise-grade Kubernetes platforms (EKS, AKS, GKE) for microservices with zero-downtime deployments and 99.99% uptime across multi-region production. Led migration of legacy applications to containerized, cloud-native architectures using Docker and Helm, improving deployment consistency and reducing environment drift via GitOps with ArgoCD. Implemented Kubernetes security and compliance controls using CIS benchmarks, OPA Gatekeeper policy-as-code, admission controllers, and RBAC. Built modular IaC frameworks with Terraform/OpenTofu/Terragrunt to improve provisioning speed. Implemented GitOps-driven CI/CD workflows integrating Terraform, Terragrunt, Jenkins, GitHub Actions, GitLab CI, and Azure DevOps for auditable infrastructure changes and faster deployment velocity. Integrated secrets management (Vault/Secrets Manager/Key Vault) into pipelines and added pre-deployment security scanning for images and manifests. Improved cloud security posture with least-pr

DevOps Cloud Engineer / AWS Engineer at Caterpillar Inc

Architected and deployed highly available cloud infrastructure for enterprise workloads using Azure services including AKS, VM Scale Sets, Azure SQL, Azure Storage, Azure Load Balancers, and Application Gateway. Designed secure Azure networking with subnet isolation, NSGs, private endpoints, and RBAC enforcement. Automated provisioning with Terraform and ARM templates, reducing environment build time. Built standardized AKS clusters with Terraform and Helm. Implemented CI/CD pipelines with Azure DevOps integrating Docker, Helm, and Terraform to accelerate releases. Engineered Kafka clusters and Kubernetes-based data platforms integrating Airflow and Azure data services. Implemented centralized observability with Azure Monitor, Prometheus/Grafana, and Elasticsearch. Automated backup and DR using Azure Backup and cross-region replication (improving RTO). Migrated VMware workloads into Azure IaaS and AKS using IaC automation.

Architected and managed multi-cloud Kubernetes platforms (EKS/AKS/GKE) using Helm and Argo CD with GitOps-driven CI/CD for zero-downtime deployments. Built secure, enterprise-grade clusters with admission control and policy enforcement (OPA Gatekeeper, CIS benchmarks), least-privilege IAM, network/security automation, and secrets management (AWS Secrets Manager/Azure Key Vault/Vault). Implemented infrastructure and application deployment automation using Terraform/OpenTofu/Terragrunt, Helm, and GitOps workflows across AWS, Azure, and GCP. Designed modular, reusable IaC components (DRY) and used Terragrunt features for DRY, remote state management, and environment promotion. Delivered end-to-end observability with Prometheus/Grafana/ELK/LoKi and security scanning for Docker images, Helm charts, and Kubernetes manifests before deployment. Developed Python/Go-based automation tools and APIs to reduce manual work and improve pipeline reliability.

Designed and deployed AWS solutions using EC2, S3, RDS, EBS, Elastic Load Balancer, Auto Scaling, CloudFormation, and IAM. Implemented secure networking with security groups as virtual firewalls, and automated provisioning using Terraform and Ansible. Built CI/CD workflows with Docker, Jenkins, GitHub/GitLab and deployed artifacts to Nexus/other registries; stored build artifacts in S3. Created AMIs using Packer across regions and managed infrastructure DRY using Terragrunt. Worked extensively with containerization and orchestration (Docker, Kubernetes) including Helm charts, production deployments, and troubleshooting. Implemented monitoring and alerting integrations (CloudWatch, Nagios/Splunk/DataDog/New Relic) and automation for backups and recovery. Supported Kafka infrastructure on AWS and integrated IaC and automation tooling using Chef/Ansible with CloudFormation.

AWS / Devops Cloud Engineer at All State Insurance

Led migration of on-premises applications to AWS using EC2, RDS, S3, VPC, IAM, Auto Scaling Groups, and Application Load Balancers, reducing overhead and improving scalability. Designed secure VPC architectures with public/private subnets, NAT gateways, encryption, IAM role-based access, and S3 versioning. Implemented IaC with Terraform and AWS CloudFormation to reduce build time and improve consistency. Built and optimized CI/CD pipelines using Jenkins, GitHub/Bitbucket, Maven, Docker, and Nexus to reduce release cycles. Deployed containerized workloads with Docker and Kubernetes/ECS where applicable. Engineered global delivery using CloudFront integrated with S3 and ALB origins to reduce latency. Implemented monitoring/alerting with CloudWatch/Datadog/ELK to reduce MTTR. Automated AMI creation with Packer and Ansible to reduce drift. Designed DR strategies with automated snapshots, cross-region replication, and backup orchestration to improve RTO. Integrated SonarQube into Jenkins an

AWS / DevOps Cloud Engineer at Manhatthan Associates

Handled migration of on-prem applications to cloud and created AWS resources with ELB and Auto Scaling for scalability and availability. Configured VPC and database subnet groups, set up S3 buckets with versioning and security, and implemented CloudWatch monitoring and alerting. Built end-to-end CI/CD pipelines using Jenkins, Docker, GitHub, and Nexus to retrieve code, build and test, and push artifacts. Deployed Jenkins servers on AWS and Azure and supported deployments for multiple environments (QA/Integration/UAT/Production). Created CloudFront/CDN distributions via CloudFormation. Coordinated with security teams for enterprise vulnerability scanning and migrated/updated monitoring dashboards and agents (including DataDog). Developed CI processes (Jenkins servers/nodes/VMs), scripting automation (Perl/Python/Shell), and CI/CD release flows.
