Wearing lots of cloud hats, infrastructure, devops, SRE! Helping RNSI optimize their cloud stack!

● Achieved a $160,000+ reduction in yearly AWS cost by implementing best-practice infrastructure redesign, reducing number of load balancers to minimum number needed, implementing host-based routing on AWS ALB, and implementing proper cost-effective and performant AWS EC2/RDS instance choices.● Improved DevOps Engineer and Developer experience by reworking existing infrastructure code to best-practice optimized state to increase code efficiency/scalability, improve code readability, add clear documentation, democratize understanding of implementation/deployment practices, and reduce number of repositories involved in deployment.● Optimized the security posture, performance, and deploy/build time of containers and EC2/ECS hosts by automating AMI replacement in terraform and upgrading container operating systems onto Alpine linux and deploying latest updates during build● Automated AWS Lambda deployment by writing terraform that built and deployed Lambda and Lambda Layer dependencies properly, reducing multi-PR process to single PR process, providing developers with a simpler method to deploy numerous Lambas● Designed and implemented proper s3 multi-tenant architecture integrating consul, terraform, AWS S3, AWS Lambda, and other services to allow streamlined management of previously challenging s3 event triggers for Lambdas● Mentored engineers both on my team and DataOps/DevSecOps team to improve infrastructure coding practices, address tech debt, help them design better infrastructure, and answer intermediate/advanced questions on terraform syntax and code design.● Provided cross-team SRE support to all Developer teams, DataOps team, DevSecOps team for SME-level questions on pipeline deployments, addressing failed builds, maintaining stability of CI/CD tooling, ensuring deployments finish properly, troubleshooting complex application issues using ELK and Datadog

Achieved a 68% reduction in AWS cost by modernizing fleet of EMR instances and EC2s while maintaining stabilityPerformed cross-region AWS Disaster Recovery Exercise of 5 business-critical applications with zero downtime Reduced monthly process man-hours by 4 hours by architecting and automating data consumption for a critical federal regulatory process on AWS S3, EC2, SQS, and an in-house java utility.Improved service response times by creating a Terraform pipeline to implement AWS Elasticache w/RedisOptimized CI/CD pipeline by converting existing AWS EC2 pipeline to terraform-based AWS ECS pipeline and dockerizing applications.Contributed Python and Terraform code to custom utility used to reduce manual interactions and automate monthly rehydration of custom AWS ASGs that ran ElasticSearchGenerated and maintained compliant IAM and S3 bucket policies in a highly granular fashion in an environment where compliance asks changed constantlyAutomated the creation of functional, compliant S3 bucket policies w/custom Terraform utilityStreamlined developer experience by converting existing custom deployment/operations tools from bash into PythonMaintained compliance with rapidly changing business/security requirements by automating SRE work into repeatable pipelines using custom terraform modules

Built a large portion of the systems/infrastructure for this small E&S Insurance start-up, including Zimbra Email server, FreePBX SIP Telephony system, OpenLDAP Server, Microsoft Active Directory Servers, VMWare ESXi hosts, Xen/KVM Virtualization hosts, Apache Tomcat Servers, Microsoft DFS File servers, Samba/NFS File Servers, Apache HTTP Servers. Automated lots of manual processess with scripting, saving days of manual labor such as: PBX boot imaging for linux servers with custom user data scripts, local admin password changes, Active Directory user creations, DNS Failover, and system status checking. Ensured CI/CD Using Jenkins automation server and Subversion version control. Performed warm-site colo failover multiple times a year with minimal downtime. Automated patch management of Linux systems using open source ops platform SpacewalkParticipate in Pen test and remediation of security findingsImplement remote user work capability through SSL VPN
