Led comprehensive modernization of infrastructure, Cloud Security, CICD and monitoring; Architected and deployed AWS multi-account infrastructure using terraform modules, implementing hub-and-spoke model to improve security posture and resource management.-Drove AWS cost optimization initiatives resulting in significant monthly savings.-Designed centralized Helm chart and reusable GitHub Actions workflows, reducing deployment time by 90% and standardizing container builds using Kaniko across all applications-Migrated company website from Netlify to AWS Cloudfront and S3, resulting in 50% cost savings while improving security, scalability, and CI/CD capabilities-Implemented AWS Account SSO using AWS Federation and Google Workplace, replacing long-term access keys with short-lived credentials to enhance security posture and access management-Executed DNS migration from GoDaddy to AWS Route53,streamlining DNS managementImplemented global application architecture utilizing Route53 latency-based routing for optimal user experience across multiple AWS regions

-Served as a team leader; Generated and prioritize work projects, and provided mentorship to junior DevOps Engineers; -Created new DevOps team Initiatives to eliminate toil and modernize CI/CD and Infrastructure. -Designed a new development platform with Kubernetes, centralized docker registry, and shared GitLab pipelines to standardize, simplify, and scale-Improved continuous deployment by 90% by designing a central helm chart which can be easily updated with new features for use with all applications, reducing duplicate code;-Designed and implemented a more secure and simple AWS Account Architecture; migrated to using AWS Federation with AWS roles over IAM users and access keys; Implemented Okta AWS CLI program for shell access -Reduced AWS account build time by 50% by creating terraform modules to build out each new AWS account with default AWS resources such as VPCs with networking, EKS, IAM roles / policies, S3 buckets, and KMS keys-Created internal website solution using Okta, Application Load Balancer, and Kubernetes, allowing developers to easily set up an internal website for the company with security features-Led cloud migration from Heroku to AWS EKS, enabling team to use the same CICD to deploy to AWS EKS and making the applications easier to administer-Incorporated Agile methodologies into DevOps process to become more organized and efficient

-Planned and prioritized work for the DevOps team; streamlined the build and deployment of docker containers to Kubernetes using GitLab-Created Kubernetes data streaming pipeline using Kafka.-Built a multi-region production Kubernetes environment with 2M+ requests daily that passed BCDR testing-Created best practices for developers to craft applications for Kubernetes, incorporating comprehensive documentation on best practices for logging and monitoring, resulting in increased development productivity.-Directed CI/CD migration from Jenkins to GitLab; decreased duplicate code and deployment time by ~70%-Design new logging platform using Fluent Bit and Elasticsearch to allow all logs to be on central location-Improved visibility and minimized incident count by creating a monitoring platform using Datadog, allowing the team to troubleshoot and fix issues faster, decreasing the time to resolution by ~80%-Achieved a 90% reduction in application testing duration through the implementation of an automated Kubernetes deployment pipeline. This pipeline facilitates the deployment of each commit to Kubernetes under the application name alongside the branch name, enabling concurrent testing with multiple deployments.
