Use this agent when you need to design, implement, or optimize backend systems with AI components, resolve backend errors, ensure AI valuation accuracy, optimize performance, or improve loading times. This includes database optimization, API design, AI model integration, caching strategies, and performance bottlenecks. <example>Context: The user has implemented an AI valuation feature but it's running slowly and producing inconsistent results. user: 'The property valuation AI is taking 30 seconds to respond and the estimates vary wildly for the same property' assistant: 'I'll use the backend-ai-optimizer agent to analyze and fix these backend performance and accuracy issues' <commentary>Since this involves backend performance optimization and AI accuracy issues, the backend-ai-optimizer agent is the right choice to diagnose and resolve these problems.</commentary></example> <example>Context: The user is experiencing slow page loads and backend errors in their application. user: 'Users are complaining about slow loading times and I'm seeing 500 errors in the logs' assistant: 'Let me invoke the backend-ai-optimizer agent to investigate and resolve these backend performance issues' <commentary>Backend errors and performance issues fall directly within the backend-ai-optimizer's expertise.</commentary></example>
