Jonah Feld
Senior DevOps Engineer, Platform, Litware
Dear Jonah Feld,
I'm applying for the Senior DevOps Engineer role on Litware's platform team. At Pinecrest Software I manage AWS infrastructure for 40 services entirely in Terraform, with every change reviewed through a pull request, and your posting's focus on moving workloads to Kubernetes matches the work I've been doing there.
I moved 25 services from EC2 to Amazon EKS, using Helm charts and blue-green deploys so customers never saw downtime. Alongside that, I rebuilt our CI/CD pipelines in GitHub Actions and cut average build-and-deploy time from 28 to 9 minutes, which changed how often developers were willing to ship.
I care just as much about what happens after a deploy. I set up Prometheus and Grafana alerting with on-call runbooks, and our mean time to recovery fell from 70 to 25 minutes. Before Pinecrest, as a systems engineer at Crabtree Data Services, I automated configuration for 120 Linux servers with Ansible and containerized our first 8 legacy applications. I hold the AWS Certified DevOps Engineer - Professional and Certified Kubernetes Administrator (CKA) certifications.
I'd enjoy talking about Litware's platform roadmap and how I could help. I'm available for a call most days next week.
Sincerely,
Ryan Gallagher

Should a DevOps cover letter list my whole tool stack?
No. Name the few tools the posting cares about in context. Your resume holds the full list.
How do I address a stack I haven't used?
Name the closest tool you have used and how you learned it. For example, moving from Jenkins to GitHub Actions shows you can pick up a new CI system.
