PROFILE
Iain Duncan
Worked on the IBM/portieris repository to modernize and secure the backend codebase, focusing on Go development, containerization, and DevOps practices. Upgraded the Go language version twice, first to 1.22 and later to 1.24.2, addressing technical debt and remediating security vulnerabilities. Enhanced build reliability by updating Docker base images, synchronizing version references across Dockerfile, Makefile, and Helm chart, and removing unreliable tools from the CI pipeline. Improved OAuth error handling and standardized error reporting for clearer diagnostics. Demonstrated a methodical approach to dependency management, security best practices, and continuous integration, resulting in a safer and more maintainable project.
