PROFILE

Jørn Ola Birkeland

Over four months, contributed to security and build automation across several repositories, notably kartverket.dev and backstage-plugin-risk-crypto-service. Established risk assessment and encryption configuration scaffolding using Kotlin, Gradle, and Dockerfile, enabling encrypted configuration management and standardized security metadata. Enhanced CI/CD pipelines with GitHub Actions and improved dependency management, including Java and Spring Boot upgrades. Developed container-based integration testing with Testcontainers, stabilizing end-to-end validation in CI environments. Delivered targeted security patches by upgrading SOPS in Docker builds, ensuring vulnerability remediation without functional changes. The work emphasized reproducible builds, secure release engineering, and compliance-ready governance for risk and encryption-focused backend services.

December 2024: Delivered security-focused scaffolding for kartverket.dev, establishing the foundation for risk-based controls and encrypted configuration management. Implemented initial risk assessment (RoS) and encryption setup with .sops.yaml and risc-default.risc.yaml, and standardized security metadata by renaming the security description file from .sikkerhet to .security. This work enhances our security posture, reduces setup time for compliant configurations, and supports ongoing governance across the repository.
