Worked on Docker build optimization and environment compatibility for the RSQKit repository, focusing on improving the Dockerfile and docker-compose.yml configurations. Applied containerization skills to reduce image build times by minimizing source code copying and refining the build context. Adjusted volume mounts and working directories to ensure consistent behavior across Linux, macOS, and Windows environments, which enhanced reproducibility for both local development and continuous integration workflows. Used Dockerfile and YAML to implement these changes, resulting in faster onboarding and smoother deployment processes. The work addressed cross-environment parity, supporting more reliable development, testing, and deployment pipelines for the RSQKit project.
