PROFILE

Stephan Butler

Stephan enhanced the interledger/rafiki repository by focusing on container security and CI/CD automation. He implemented non-root execution for Docker containers, configuring services to run as the 'rafiki' user and tightening file permissions to reduce privilege escalation risks. Using Docker, Shell scripting, and YAML, Stephan improved compliance readiness by making container defaults auditable. In a separate effort, he refactored the CI/CD pipeline to introduce hierarchical major and minor version tagging, streamlining release traceability and rollback. He also updated GitHub Actions workflows to reduce PR noise, resulting in clearer deployments and a more efficient contributor experience. The work demonstrated strong DevOps depth.
