PROFILE
Iain Duncan
Iain Duncan focused on modernizing and securing the IBM/portieris repository by upgrading the Go language version and Docker base images, addressing technical debt and known vulnerabilities. He implemented Go 1.22 and later 1.24.2 upgrades, ensuring compatibility and leveraging new language features while remediating security issues such as CVE-2025-0395. Iain synchronized version references across Makefile and Helm chart to maintain build and deployment consistency. He also improved OAuth error handling and streamlined the build process by removing unreliable tools. His work demonstrated depth in Go development, containerization, and DevOps, resulting in a more robust, secure, and maintainable backend system.
