Dear Hiring Manager,

I'm excited to apply for the Senior Cloud Engineer role on your platform team. I led a lift-and-shift migration of 80 legacy services to AWS that cut our monthly infrastructure spend by 34% while improving average response time by 25%.

I write infrastructure as code in Terraform and manage container workloads on EKS across three regions, currently supporting around 200 microservices. I built the CI/CD pipeline in GitHub Actions and CodeDeploy that took our release cadence from weekly to multiple times a day, and I hold the AWS Solutions Architect Professional certification.

I've followed your recent move toward a multi-region active-active setup, and it's exactly the kind of resilience problem I enjoy solving. I'd welcome the opportunity to discuss how my migration and cost-optimization experience could support that work.

Sincerely,

Sofia Almeida
