PROFILE

Erik Heeren

Worked on the openbraininstitute/aws-terraform-deployment and entitycore repositories, delivering features and fixes that improved cloud infrastructure reliability, security, and automation. Focused on AWS and Terraform, the work included explicit environment-specific Docker image configuration, enhanced HPC provisioning with new SSM endpoints and resource policies, and sandbox environment cleanup to streamline maintenance. Security was strengthened by integrating automated Python dependency vulnerability audits into the CI/CD pipeline using pip-audit and GitHub Actions. Across four months, addressed deployment workflow bugs, updated infrastructure as code, and implemented IAM policy management, using HCL, Shell, and YAML to ensure robust, maintainable, and secure DevOps practices.

January 2025: Focused on stabilizing the deployment environment for the Virtual Lab Manager in the AWS Terraform deployment pipeline. Key feature delivered: explicit Docker image URL configuration – removed default image URL and defined separate URLs for staging and production to guarantee the correct image is deployed at each stage. Major bug fixed: prevent misdeployment caused by default image URL. Commits: 974453a7c3928edb2a7c7fbecc5a88662049a216. Impact: reduces deployment errors, improves environment parity, and enhances reliability of Terraform-driven deployments. Technologies/skills: Docker, environment-specific configuration, Terraform deployment workflows, release hygiene.
