During September 2025, contributed to backend stability and deployment flexibility across two repositories. In langgenius/dify, addressed a runtime error by ensuring the curr_message_tokens variable was properly initialized, preventing message processing failures and improving reliability. In mudler/LocalAI, implemented a feature allowing users to override the HuggingFace API endpoint through the HF_ENDPOINT environment variable, supporting alternative mirrors and self-hosted instances for API scans and model resolution. These changes were delivered using Python and Go, with a focus on API integration, configuration management, and environment variable handling to support diverse deployment scenarios and enhance maintainability across both codebases.
