Tangxiaolong
Tang Xiaolong developed and maintained core backend features for the LianjiaTech/bella-domify repository, focusing on secure, scalable document parsing and file processing pipelines. Over three months, Tang unified the document parsing API, implemented per-type caching, and expanded support to include DOCX parsing and DOCX-to-PDF conversion. The work involved extensive code refactoring, dependency management, and security hardening, including token validation and input checks. Tang also restructured HTTP worker lifecycles and Kafka consumer initialization to improve concurrency and reliability. Using Python, FastAPI, and Kafka, Tang delivered robust, maintainable systems that enhanced document workflow scalability, security, and developer productivity across the codebase.

Aug 1, 2025Month 2025-08: Strengthened system reliability and scalability by restructuring HTTP worker lifecycle and enforcing safe Kafka consumer initialization. Implemented main-worker controlled Kafka startup, enhanced thread monitoring, and auto-restart for background parsing tasks. Increased HTTP process count to improve concurrency and reduce latency. Result: fewer duplicate messages, lower downtime, and faster throughput for end users.
