Projekthistorie
Setting the technical direction of the platform after the Norwegian business was carved out. Writing architecture plans for hybrid cloud, digital sovereignty, managed data services, IoT platform, carbon reporting, and steering implementation across roughly 70 repositories. Extended the IaaS platform (managed Kubernetes, HPC clusters, load balancers, NFS filesystems), migrated all cluster ingress to Traefik without downtime, and built the new customer-facing stack: REST API (FastAPI), SPA (Vue 3/Quasar), Terraform provider, CSI driver, cloud-controller-manager in Go, and usage-based billing.
Replaced the aging and inefficient OpenStack backend of a fleet of 500 nodes and 4000 GPUs serving hundreds of customers. Settled on KubeVirt for VM hosting with bespoke operators and controllers for networking and storage. Used completely ephemeral hosts based on Flatcar Linux, booted from network in a full GitOps setup. Technologies used: SPDK, Kopf, Flux, KubeVirt, Prometheus, Jaeger, VPP, Ceph, Infiniband, GitHub Actions, BDD.
Enabled customers to create or migrate their applications to AWS. Took a leadership role in all projects involved. Focus on migrations and data projects. Technologies: AWS Amplify, AWS Managed Airflow, dbt, Terraform, CloudFormation, Snowflake, Oracle SQL, NetApp Storage.
