Over a three-month period, contributed to openclaw/openclaw and moltbot/moltbot by focusing on backend reliability and internationalization. Addressed system resilience in openclaw/openclaw by refining failover logic for ZhipuAI quota events and stabilizing token usage accounting in the Claude CLI, using TypeScript and JavaScript to improve error handling and session management. Enhanced moltbot/moltbot’s memory-wiki by implementing Unicode-aware slug handling, expanding language support and preventing filename overflows. Emphasized robust testing practices to cover edge cases and regressions, ensuring maintainable code. The work demonstrated a methodical approach to backend development, API integration, and full stack testing across diverse technical challenges.
