Worked on the paddlepaddle/paddleocr repository to deliver a feature enabling OCR model storage location customization through environment variables, supporting flexible and reproducible deployments. The implementation removed hard-coded paths and introduced environment-variable driven configuration, allowing users to specify a base directory for model storage using variables such as PADDLE_OCR_BASE_DIR. This approach improved deployment consistency across development, staging, and production environments, and facilitated container-friendly deployment patterns. The work involved Python programming, environment configuration, and thorough documentation updates. No major bugs were addressed during this period, with the primary focus on enhancing operational efficiency and deployment flexibility for OCR workflows.
