Dear Hiring Manager,
I am excited to apply for the DevOps Engineer position at Northgate Cloud. With 6+ years of experience automating delivery and running production infrastructure, I am interested in helping your team ship safely and operate reliably. Throughout my career I have focused on treating infrastructure as code, building dependable CI/CD pipelines, and making systems observable.
In my current role at Cobalt Freight, I manage CI/CD with GitHub Actions, containerize services with Docker, run workloads on Kubernetes, and provision infrastructure with Terraform on AWS. Recently I rebuilt our deployment pipeline with containerized builds and staged rollouts, which cut average deployment time from 40 minutes to 9 minutes and reduced failed deploys significantly. I also added Prometheus and Grafana dashboards with actionable alerts that lowered mean time to recovery during incidents. I treat runbooks and rollback procedures as essential practices, not afterthoughts.
What interests me about Northgate Cloud is the opportunity to work where delivery speed, reliability, and observability directly affect every engineering team. I would be glad to contribute my experience with CI/CD, Docker, Kubernetes, Terraform, AWS, and monitoring to help your team ship with confidence. I enjoy work where strong automation makes the whole platform safer and faster.
Sincerely,
Sofia Marchetti
