Worked on the Nine-Minds/alga-psa repository to deliver an independent Docker Compose environment configuration, enabling NODE_ENV and APP_ENV to be set separately with a robust fallback mechanism. This approach allowed for environment-specific settings across development, staging, and production, reducing the risk of misconfiguration and manual intervention. The solution was implemented through updates to YAML-based docker-compose files, leveraging skills in Configuration Management, DevOps, and Docker. By ensuring NODE_ENV defaults to APP_ENV when unset, the work improved deployment reliability and environment parity, supporting smoother CI/CD processes and enhancing flexibility for future environment-specific deployments without introducing new bugs.
