Worked on stabilizing the web environment configuration for the AppFlowy-IO/AppFlowy-Cloud repository by addressing a critical issue with environment variable substitution in Docker-based deployment scripts. Focused on correcting the AF_BASE_URL placeholder within the env.sh script, ensuring that the variable is accurately replaced during build processes. This adjustment reduced build-time and configuration failures, leading to more reliable deployments and a smoother developer experience. Utilized DevOps practices and shell scripting to debug and review code, emphasizing environment variable management and CI/build hygiene. The work demonstrated attention to deployment reliability and contributed to consistent configuration across multiple environments for the project.
