PROFILE
Rasmus Thorslund
Over seven months, Thorslund engineered automation and configuration management solutions for the SUNET/puppet-sunet repository, focusing on infrastructure as code and operational reliability. He developed automated workflows for MicroK8s node maintenance, centralized secret and certificate management, and dynamic monitoring configurations using Puppet, Bash, and YAML. His work included refactoring environment variable handling for Edusign deployments, parameterizing load balancers for flexible scaling, and enhancing deployment pipelines with scripting and Docker integration. By leveraging tools like Hiera and Nagios, Thorslund reduced manual intervention, improved maintainability, and established consistent, environment-driven configurations, demonstrating depth in DevOps practices and disciplined, maintainable code delivery.
