AI Agent Developer | AI Automation, RAG, Voice Agents | n8n, LangChain

I build AI agents, automations, and AI-powered SaaS that actually survive production — 10+ years full-stack, Top Rated Plus, 99% Job Success, 4,000+ hours, $3M+ delivered on Upwork. Most AI projects die between the demo and the real world. My focus is the part that keeps them alive: evaluation, guardrails, error handling, human-in-the-loop fallbacks, and clean architecture — so your agent doesn't hallucinate to customers or silently break when an API changes. WHAT I BUILD - AI Agents & Multi-Agent Systems — LangGraph, Pydantic AI, custom agentic loops, MCP servers - AI Voice Agents — inbound/outbound calling, appointment booking, lead qualification (Twilio-based stacks) - RAG & AI Knowledge Bases — chunking, vector search, citations, "I don't know" behavior instead of hallucinations - Workflow Automation — n8n, Make, custom Node.js/Python pipelines with logging and retry logic - AI Chatbots & Assistants — web, WhatsApp, Slack; context-aware and grounded in your data - LLM Integration — OpenAI, Anthropic Claude, Gemini, and local/open-source models (Ollama, Llama) when privacy or cost demands it - AI features inside your existing platform — Shopify, WordPress/WooCommerce, Wix, Webflow; I've shipped on these platforms for a decade, AI is the new layer, not a rebuild - CRM & Business Tool Automation — GoHighLevel (GHL), HubSpot, Zoho, Airtable, Notion, Slack, WhatsApp Business; AI-powered lead follow-up, SMS/email reactivation campaigns, pipeline automation, and appointment booking inside the tools you already run - SaaS Platforms — MVP to scale: React/Next.js, Node.js, Python/FastAPI, AWS/GCP, Docker, CI/CD HOW I WORK I develop AI-natively: Claude Code, Cursor, and Codex do the heavy lifting; my value is the senior judgment that validates what they produce — security, maintainability, and architecture that your next developer can actually read. If you're hiring someone to direct AI coding tools, that's literally my daily workflow. Every engagement includes: clear acceptance criteria up front (accuracy targets, latency, channels), transparent API/usage cost planning, documented handover, and post-launch support. WHAT YOU GET Not a demo. A system with measurable results — hours saved, tickets deflected, calls booked — that keeps working after I'm gone (though most clients keep me on retainer to make it better).
