Worked on the dataelement/bisheng repository to address a critical user experience issue in chat-based workflows. Focused on frontend development using React, JavaScript, and TypeScript, the primary task involved fixing a bug that caused abnormal page scrolling after completing a workflow session. The solution stabilized chat input positioning, preventing visual glitches and ensuring smoother multi-turn chat interactions. This targeted update improved the reliability and usability of the chat interface without introducing new features. Clear commit messages and issue traceability were maintained throughout, supporting future debugging and audits. The work demonstrated attention to detail in UI development and code quality.
