I build LLM-powered systems that work in production, not just in demos. Agents that reason, RAG pipelines that retrieve accurately, voice AI that handles real conversations.

If you are building an AI product or automating a workflow with LLMs, I can take it from idea to deployed system.

What I specialize in:

🧠 LLM Agents and Agentic Workflows
Multi-agent systems, autonomous tools, and complex orchestrations using LangChain and LangGraph. I build agents that plan, use tools, delegate to sub-agents, and handle edge cases without falling apart.

🔍 RAG Systems and Knowledge Retrieval
Production-grade RAG pipelines using ChromaDB, Supabase, or Pinecone. Hybrid search, re-ranking, context grounding, and retrieval evaluation baked in. Your LLM stops hallucinating and starts answering from your actual data.

🎙️ Voice AI and Real-Time Conversational Systems
Voice agents built with ElevenLabs, Whisper, Livekit, and Vapi. Low-latency, interruption-aware, and trained on your domain knowledge.

🔗 MCP and Tool Integrations
Model Context Protocol servers, API tool integrations, and custom function-calling pipelines that connect your LLM to the systems it needs to act on.

📦 Models I work with:
OpenAI, Anthropic Claude, Google Gemini, DeepSeek, Mistral, and open-source models. I pick what fits your use case and budget, not just the default.

Why clients come back:

✅ I think about the business problem first, then the AI solution
✅ I write clean, documented code you can maintain after I am done
✅ I communicate clearly and flag problems early, no surprises
✅ I have delivered production AI systems across logistics, healthcare, and SaaS

Recent projects:

• AI assistant that automates report generation across departments
• Voice agent trained on proprietary product documentation
• Multi-agent platform coordinating operations for a logistics startup
• Real-time RAG system connecting an internal knowledge base to LLM search
