James Shellis contributed to the CPS-Innovation/Polaris repository by delivering platform reliability, security, and user experience improvements across backend and frontend systems. He upgraded legacy .NET tooling and migrated the application to .NET 8, refactored project structure, and enhanced CI/CD pipelines using Bash and Terraform for infrastructure as code. James optimized entity deletion workflows to reduce data transfer, stabilized Nginx-driven document retrieval, and improved authentication by supporting client credentials flow. He also addressed UI navigation issues in React and TypeScript, enforced code quality with ESLint, and implemented secure routing fixes, demonstrating depth in backend development, DevOps, and modern JavaScript engineering.

Oct 1, 2025October 2025: Delivered a critical CMS redirect fix and reinforced the CMS launch flow in Polaris, addressing a misrouting that could affect user authentication and onboarding. Implemented a temporary redirect path correction so /launch/cms now routes to /auth-refresh-inbound on the CMS domain instead of /task-list, enabling a stable launch experience until the homepage is implemented. This work reduces user friction, stabilizes the early launching flow, and provides a reversible workaround aligned with project timelines. Key commit reference: ec1f0b5c1f5d2039a91d55b0c7bf77b50616f86b ("Use CWA for C Button Launch until homepage complete (#1759)"). Technologies/skills demonstrated include backend routing/redirect handling, CMS domain routing, temporary workaround strategy, and clear traceability to issue #1759.
