Node.js + Claude API developer to review and fix an AI feature

I'm a non-technical founder who built a web app in Node.js using Claude Code, without any coding background. The app is close to finished, but its core feature isn't working reliably. Every time Claude Code fixes one issue, something else seems to break. The feature relies on the Claude API and web search across multiple steps to research information and generate content. Some steps return empty results, some API calls fail, and the overall output is inconsistent. **What I need help with:** - Find and fix the underlying issues so the feature works reliably from start to finish. - Show me the working feature and explain the changes in simple terms. **You're a good fit if you:** - Work primarily with Node.js. - Have hands-on experience integrating the Claude or OpenAI API into production applications. - Have experience debugging and improving AI-generated code from tools like Claude Code, Cursor, or Lovable. - Can communicate clearly and explain technical issues to a non-technical founder. Please also include: - How you'd approach diagnosing and fixing the issue. - Your estimated timeline. - Your price or expected budget.
