Managed several Kubernetes clusters provisioned using Cluster API as well as all cluster-level components running on them in both AWS and GCP.Leveled up Bazel usage in multiple areas and implemented significant additional tooling, most notably a Buildbarn remote execution cluster to significantly increase build speeds.Redesigned CI/CD using dynamic pipeline generation in Buildkite to remove excessive boilerplate configuration, enforce safe and efficient defaults, and greatly simplify on-boarding of new services.Maintained the tool that all developers used to write and deploy Kubernetes manifests and implemented robust rollback functionality.Wrote and implemented a Kubernetes operator to support safe, controlled rollouts for StatefulSets based on Prometheus metrics.Migrated all legacy Terraform to a more sustainable model and implemented Atlantis for it to be fully self-service.

Embedded with development teams to introduce them to service ownership principles, evaluate the current state of their services, and implement improvements to their services.Heavily contributed to the first implementation of the new Kubernetes-based compute platform, which turned into the future of compute at Slack.Drove the implementation of the SLO program which lead to a strong cultural shift towards reliability within multiple product development teams.Developed a web-based internal tool to automate the creation and updating of dashboards, SLOs, and alerts for service owners that led to a massive increase in visibility into service issues.Rebuilt the image proxying and file serving services on the new compute platform, making the services much more robust against overload and trained the team that eventually took them over.Performed load testing across various areas of the product which allowed for the safe on-boarding of the 2 largest companies using Slack now.Reduced the time it took to deploy the internal encryption service from 5 hours to 30 minutes, removing a large point of toil for the team while at the same time making the deployment process much safer.Developed a web-based internal tool for service owners to scale AWS Auto Scaling groups, enabling a higher level of service ownership while ensuring guard rails were in place.

Working with the College of Engineering to support the various college systems including an oVirt virtual environment, Ceph cluster, and multiple RHEL and Windows Servers.Integrated oVirt with Ceph using Cinder and developed migration tooling.Deployed initial implementation of Zabbix to assist in the monitoring of the college infrastructure.Set up Rundeck to aid with the automation of Ansible and other tasks.Researched and implemented various other solutions to better serve the needs of the college.

Expanded functionality of internal Python libraries and wrote unit tests.Improved efficiency of internal VM deprovisioning pipeline by over 85%.Expanded internal VM provisioning pipeline to support Google Cloud Platform.Implemented a profiling system to time Chef runs.Worked with the QA team to upgrade and improve the QA environment.Implemented all necessary changes to upgrade internal and external systems to new OS and software versions and started the global roll-out.

Learned and used Chef to deploy JIRA and Alerta in AWS.Architected both to fit the needs of the rapidly-changing environment so they could be rebuilt from scratch at any time.Used multiple AWS services to securely deploy the applications.Tested multiple monitoring systems and implemented Datadog monitoring into the JIRA deployment.Learned the basics of Ruby to improve the automation of an internal system.Did penetration testing on an outdated Java application and reported findings.

Migrated to and implemented current email system, deployment system, printer server/accounting system, and web server.Assisted in the upgrade to the current virtual environment, wireless infrastructure, and core networking.Maintained multiple servers and completed multiple projects to improve infrastructure, strengthen security, and better serve the needs of the school.Trained current IT Director and provide remote support when needed.

Upgraded and improved infrastructure and security for upcoming animated film.Implemented multiple systems including the current wireless infrastructure, a render farm, and multiple NAS systems.
