Worked on the LianjiaTech/bella-domify repository to enhance the reliability, security, and observability of its backend systems over a two-month period. Focused on improving the PDF parsing pipeline by introducing robust handling for missing text, excluding watermarks, and implementing Kafka thread monitoring with automatic restarts. Strengthened API key management by externalizing keys to environment-based configuration, removing hardcoded secrets. Additionally, improved server API observability by routing thread status logs to structured application logging, replacing direct print statements. Leveraged Python for backend development, emphasizing API integration, logging, and configuration management to deliver maintainable, secure, and easily monitored infrastructure components.
