About Sarah

I'm a Cloud & DevOps Engineer who came up as a software engineer before moving full-time into infrastructure — so I understand both the applications running on your systems and the platform underneath them. I work hands-on with AWS and GCP: CI/CD pipelines, Kubernetes, Infrastructure as Code (Terraform), monitoring, and automation.
For you, that means fewer deployment surprises, infrastructure that's actually documented and reproducible, and someone who can talk to your developers, not just your servers.
How I can help:

CI/CD pipeline setup — GitHub Actions, GitLab CI
Kubernetes deployment and container orchestration (GKE, EKS)
Infrastructure as Code with Terraform
Monitoring and alerting — Prometheus, Grafana, ELK, CloudWatch
Cloud security basics — IAM, secrets management, VPC hardening

What's different about me: I've built and run production infrastructure as a founder, not just followed a runbook — I currently operate the full GCP infrastructure for my own SaaS platform, end to end. Before that, five years as a software engineer working alongside DevOps teams taught me how infra decisions actually affect the code running on top of them.
Best fit for:

Startups and small teams who need a CI/CD pipeline built or fixed
Terraform-based infrastructure setup on AWS or GCP
Kubernetes cluster setup with sensible defaults
Adding real monitoring/alerting to a team that's flying blind

Operating as a French micro-entrepreneur — I invoice directly, no third party or visa sponsorship required for EU/UK clients.
