PROFILE

Derek Yau

Worked on the bcgov/HOUS-permit-portal, delivering features that improved deployment safety, environment stability, and developer experience. Focused on CI/CD automation, Docker-based local development, and OpenShift deployment workflows, the work included upgrading Ruby environments, optimizing Docker Compose setups, and enhancing debugging capabilities. Used JavaScript, Ruby, and YAML to streamline build processes, standardize release versioning, and align development, testing, and production environments. Addressed authentication robustness and resource tuning for services like Elasticsearch and Redis, resulting in safer, auditable releases and more resilient infrastructure. The approach emphasized maintainability, traceability, and operational efficiency across the full stack and deployment lifecycle.

January 2025: Implemented CI/CD reliability improvements and versioning standardization for the HOUS-permit-portal, delivering clearer deployment traceability and safer releases. The changes ensure the GITHUB_SHA in production/testing workflows reliably reflects the checked-out commit and standardize release identifiers by using '@' to separate branch name from the git SHA, enabling faster diagnosis and auditing across environments.

Month 2024-12 for bcgov/HOUS-permit-portal: Delivered deployment safety improvements, release management enhancements, and production hardening with a focus on business value and maintainability. Highlights include deployment safety via GitHub Actions branch confirmation, deterministic release versioning by injecting VITE_RELEASE_VERSION into Docker at runtime, and automatic SHA detection for dev/test environments. Production readiness was strengthened through removal of Dev/Test limits and scaling of Redis/Elasticsearch, along with code and config hardening across the stack. The work also improves authentication robustness via an explicit-case OmniAuth UID/Username refactor and prepares for stable UX with runtime-visible registration URLs and UI tweaks. Business impact: safer, auditable releases; improved environment parity; increased resiliency and scalability of core services; streamlined operational workflows; and clearer ownership of release/versioning across pipelines.
