As a seasoned DevOps Engineer, I bring a strong track record of designing, building, and optimizing scalable cloud environments. I'm passionate about implementing DevOps principles and driving infrastructure improvements to elevate performance, security, and cost-efficiency.Key Projects: Go to Market Demo Environment: Reimagined the demonstration environment for a full suite application, transitioning from Elastic Container Service (ECS) to Kubernetes, and employing Terraform for the creation of AWS services. This allowed comprehensive end-to-end demos of our suite for our sales team. This project necessitated extensive cross-team coordination and the establishment of helm charts and helmfile deployments for Kubernetes services.Cost Optimization: Conducted a thorough analysis of our entire RDS infrastructure, leading to strategic planning and purchase of Reserved Instances (RIs), and elimination or reduction of unnecessary instances, slashing costs by 70%. Further reductions in cost were compounded through identifying and removing unused and unneeded resources, optimizing instance sizes, and consolidation. In addition to these core projects, my work includes: Implementing GitOps into our CI/CD pipelines via ArgoCD Developing application infrastructure for software development teams and creating templated GitHub repositories for Django applications. Actively participating in on-call rotation, debugging, troubleshooting, and resolving priority incidents. Refactoring Terraform, adding new features like SSM parameters, and upgrading Kubernetes clusters. Designing and enhancing CI/CD pipelines using GitHub Actions and Jenkins. Setting Team Monitoring and Alerting standards to ensure smooth operations and quick response to incidents leveraging DataDog, Sentry, Prometheus, and moreCore Skills:AWS | Terraform | Kubernetes | ArgoCD | CI/CD | Jenkins | Git | Cost Optimization | Project Management | Python (Django) | SRE

AWS and Kubernetes Projects: Led the migration of client-managed K8s clusters into AWS EKS, which streamlined operations and enhanced performance. Developed AWS CloudFormation templates to automate the deployment of Highly Available and Fault Tolerant GitLab environments. Utilized Terraform for efficient management of AWS resources encompassing networking, compute, and persistent storage. Designed and implemented an automated Blue/Green deployment strategy for client applications in Kubernetes. Successfully implemented Role-Based Access Control (RBAC) using AWS IAM with Kubernetes service accounts and roles.Software Development: Made significant contributions to a Python-based proprietary client service. Authored various ad hoc Python and Bash scripts to streamline CI/CD activities. Crafted Docker images and Dockerfiles for various services, automated testing, and ad hoc tools.CI/CD Projects: Redesigned and automated EKS deployments via Jenkins, using Job DSL and shared libraries. Developed automated Terraform pipelines and improved pipeline configuration management. Engineered complex CI/CD pipelines for Windows and Linux environments in GitLab, including the setup of organizations, SAML and LDAP integration, and project migrations to GitLab and GitLab CI.Continuous Learning: Completed courses on GitHub Actions, GraphQL, and Golang, demonstrating my commitment to upskilling and staying abreast of industry trends.Core Skills:AWS | Kubernetes | Terraform | CloudFormation | CI/CD | Jenkins | GitLab | Python | Docker | RBAC | Bash Scripting
