I architect multi-agent AI systems using CrewAI and LangChain that break complex tasks into coordinated, parallel workflows — with each agent specializing in a role. Ideal for research pipelines, document processing, legal analysis, or any multi-step task that a single LLM call cannot handle reliably.

Agent Architecture Design Design the agent hierarchy, role assignments, and coordination logic for your use case. Includes task decomposition, inter-agent communication patterns, and deciding which tasks require tool use vs. pure reasoning.

Tool Integration & External API Connections Equip agents with the right tools — web search (Tavily), document retrieval, SQL execution, calendar APIs, or any external service your workflow needs. Each tool includes error handling and fallback logic.

Intent Classification & Query Routing Build a routing layer that classifies incoming requests and directs them to the right agent or sub-pipeline. Prevents unnecessary LLM calls and ensures each query is handled by the most appropriate specialist.

Persistent Context & Conversation Management Implement memory and state management so agents maintain context across multi-turn conversations, follow-up questions, and refinement requests without losing earlier information.

Anti-Hallucination & Output Validation Apply multi-layer output validation: prompt constraints, tool verification, and structured output parsing. Each agent's output is checked before being passed to the next stage in the pipeline.
