  • Build and enhance multi-agent orchestration pipelines with conditional routing, state management, and error recovery
  • Develop RAG pipelines with hybrid search (semantic + keyword), re-ranking, and Reciprocal Rank Fusion
  • Implement tool-calling agents with parallel API execution, sequential enrichment chains, and summarization
  • Build real-time streaming capabilities (WebSocket / SSE) for conversational AI Integrate with Azure OpenAI APIs with circuit breaker patterns and fallback chains
  • Implement prompt engineering and dynamic prompt management (DB-backed with in-memory caching)
  • Design and implement multi-modal AI features (image analysis with vision models)
  • Write production-quality Python code with error handling, logging, observability, and unit tests
