What I'm looking for

I'm looking to build and operate reliable cloud platforms where automation, observability, security, and operational ownership matter, ideally in complex production environments.

At the Swiss National Bank, I’m the sole DevOps engineer for the web platform, owning availability, automation, network and DMZ architecture, and the central observability platform. I automate provisioning and deployments with Git and GitLab CI/CD and migrated log ingestion from Logstash to Vector.

Previously at Valtech Mobility, I co-owned nine AWS and Azure platform projects serving more than 30 million connected vehicles, leading monitoring, alerting, Kubernetes, Terraform, and customer onboarding work for Volkswagen Group brands. I also built and operated a Python-based distributed transcoding pipeline at TV1, with a focus on production operations, on-call readiness, postmortems, and capacity and cost planning.
