> What I do

I take the work your team shouldn’t be doing — and ship the AI that does it reliably

Most AI projects stall at the demo. I build the unglamorous parts — guardrails, evals, observability, human-in-the-loop — so the system actually runs in production and your team trusts it with real work.

Agents that act, not chat

Autonomous LangGraph/multi-agent systems that research, decide, and take actions across your tools — with human approval on the risky steps.

Voice AI that books & qualifies

Real-time phone agents with sub-second latency, calendar/CRM integration, and clean human handoff.

RAG that answers from your data

Company copilots and document Q&A that cite sources and don’t hallucinate — hybrid search + reranking + verification.

Four ways I put AI to work for B2B teams

AI Agent Development

I design and build autonomous LangGraph/LangChain agents and multi-agent systems that research, decide, and act across your workflows — with human-in-the-loop control, evals, and observability so they hold up in production.

Voice AI Agents

I build real-time conversational voice agents that answer and place calls, hold natural multi-turn conversations, take actions in your systems, and hand off to a human when it matters — with sub-second latency so callers never feel like they are talking to a robot.

RAG & Knowledge Bases

I build retrieval-augmented chatbots and document Q&A systems that search your real knowledge — docs, wikis, tickets, contracts, PDFs — and answer with linked sources. Hybrid search, reranking, citation verification, and evals so the answers hold up when your team relies on them.

AI Workflow Automation

I automate the manual, copy-paste workflows that eat your week — ops, GTM, and back-office — using n8n, Make, and Zapier for the plumbing and custom Python or LangGraph where the logic gets bespoke. AI-in-the-loop for judgment calls, humans in control where it matters.

From day one, he set the tone with a detailed video proposal... He executed quickly, handled every revision without friction, and delivered an avatar that nailed what I wanted. The level of customization is excellent — voice, clothing, positioning, and backgrounds are all dialed in. Already produced a strong ROI.
