Worked on the Tencent/WeKnora repository over two months, delivering four features and resolving one bug with a focus on reliability and performance. Improved deployment stability by refining API routing and frontend API base URL handling, ensuring correct operation behind path-prefix reverse proxies. Enhanced backend ingestion pipelines by introducing robust error handling and optimizing retry logic for batch processing. Upgraded the search API to support broader client compatibility and explicit error feedback, while implementing a partial HNSW index to accelerate vector queries. Leveraged Go, SQL, and TypeScript, applying skills in API development, concurrent programming, and performance optimization to strengthen system scalability.
