\item{Regularly contribute to and maintain the Network Services Gateway and API, which provides Network-as-a-Service functions using a micro-services stack, leveraging SDN with F5 load balancing. Services include self-service application migrations, load balancing, DDI, firewall, advisories, and other network services, servicing nearly 10,000 internal applications. Automation reduces the operator time necessary to deploy datacenter applications from days to minutes.}
\item{Completed migration of Signal platform from GCP Cloud Run to Kubernetes (GKE).}
\item{Currently implementing Ford's Google Cloud Platform infrastructure using Terraform, and integrating it into the existing datacenter automation tooling.}
\item{Installed and configured Istio service mesh using RBAC integrated with Google IAM to serve public and internal endpoints.}
\item{Delivered network service goals for brand and marketing sites for the Bronco and Mach-E product launches.}
\item{Developed and maintained infrastructure as code using Terraform with hosting from GCP, AWS, Heroku, and Salesforce.}
\item{Helped lead real-time troubleshooting efforts during major product launches.}
\item{Integrated Datadog monitoring (logs, metrics, APM, RUM, SIEM) with our systems.}
\item{Developed and supported DNS migration automation for thousands of campaign-based URLs, eliminating tens of hours per migration.}
\item{Established standards for and continuously improved CI/CD using CirleCI and Github.}
\item{Helped define and automate statistics collection for team's service goals using Grafana and Prometheus, and currently working to create self-service statistics reporting for internal application customers.}
\item{Established standard deployment model for microservices hosted in Kubernetes using Helm and Terraform.}
\item{Developed and maintained the CI/CD stack for NSG's APIs and web applications, using Docker, node.js express middleware, BASH, and Quay.io, freeing up days of time per application deployment.}
\item{Established and maintained environment and configuration standards for NSG linux systems and containers, and developed BASH programs to automate operations and node maintenance across cloud architecture, reducing the time to reconfigure cluster applications from about 1 day to about 30 minutes.}
\item{Developed APIs that automate advisories and Webex messaging, and load-balanced service discovery. This allowed customers to define automated service alerts that generate application-level advisories and team-based Webex alerts, removing significant human resources from the advisory process.}
\item{Established standard build environments for our NodeJS, Terraform, and Python projects using containers suitable for local development and automated build environments.}
\item{Documented network services and network service APIs for Ford's app owners and cloud and fulfillment teams, operational software for our development team, and developed and led training to teach new developers to replicate our micro-services stack.}
\item{Helped establishment standards for, interview, and hire SRE candidates.}
