Cato Olsen developed and maintained backend services and infrastructure for the navikt/testnorge repository, focusing on secure authentication, CI/CD automation, and robust configuration management. He implemented features such as Vault-based secret handling, JWT validation, and automated deployment pipelines using Java, Spring Boot, and GitHub Actions. His work included improving local development environments with Docker and Kubernetes, enhancing observability through logging and health checks, and streamlining onboarding with comprehensive documentation. By addressing configuration drift, hardening security, and enabling reliable cross-service integrations, Cato delivered stable, production-ready solutions that reduced operational risk and improved developer productivity across multiple environments and workflows.

October 2025 performance for navikt/testnorge focused on CI/CD modernization, dev tooling, test proxy enhancements, and authentication integration. Delivered manual deployment workflow controls, removed deprecated workflows, improved local Valkey development with docker-compose setup, expanded test configuration with a new testnav-dolly-proxy, stabilized alerting with Slack webhook fix, and migrated authentication to AzureNavTokenService with updated tests. These changes reduce deployment risk, speed up local development, improve test coverage, and strengthen security and resilience across the stack.
