PROFILE

Lassi Virtanen

Over a two-month period, contributed to the fmidev/helm-charts repository by developing and enhancing Helm charts for Kubernetes deployments. Built the initial Deployment Helm Chart for obsapi, provisioning Kubernetes resources such as Deployments, Services, and ConfigMaps to standardize logging and database connectivity across environments. Improved deployment security and flexibility by introducing dynamic templating for logging and TNS names, removing hardcoded secret volumes, and simplifying security contexts. Addressed a logging configuration bug to ensure robust log level determination. Leveraged skills in DevOps, Helm, and Kubernetes, with extensive use of YAML for configuration management, supporting scalable, reproducible, and secure deployments.
