Project details
You will get a production-grade multi-agent AI system built with LangGraph, FastAPI, and the full LLM stack. I specialize in autonomous agent pipelines that run reliably in production, not demos or prototypes.
Every system I deliver includes: multi-agent orchestration with tool-calling and memory management, FastAPI backend with REST endpoints, Supabase or PostgreSQL database integration, Docker containerization, Railway or AWS deployment, error handling, monitoring, and full documentation.
Recent results from live systems: 77% cost reduction on customer support operations, 95% faster invoice processing with 98% GPT-4o extraction accuracy, 85% faster appointment booking with 100% after-hours coverage.
Starter tier covers a single-agent MVP. Standard tier adds multi-agent LangGraph orchestration with full deployment. Advanced tier delivers an enterprise-grade system with human-in-the-loop escalation, audit trails, and custom integrations.

👨💻 5+ Years Building Production AI Solutions
Businesses come to me when they need autonomous AI systems that actually run in production, not demos or prototypes.
I build multi-agent pipelines, AI voice agents, and intelligent workflow automations using Python, LangGraph, CrewAI, FastAPI, and the full LLM stack (GPT-4o, Claude, Gemini). Everything I deliver is Docker-containerized, deployed on Railway or AWS, monitored, and documented.
Recent results from live production systems:
- 77% cost reduction on customer support operations ($12K to $2.8K/month)
- 95% faster invoice processing with 98%+ GPT-4o extraction accuracy
- 85% faster appointment booking with 100% after-hours coverage
- 83% time savings on bookkeeping automation ($1,200 to $130/month)
WHAT I BUILD
Multi-Agent Systems
LangGraph and CrewAI orchestration, tool-calling agents, memory management, self-evaluation loops, MCP and A2A protocol integration, Pydantic AI, AutoGen. Built for enterprise scale with full audit trails and human-in-the-loop escalation.
AI Voice Agents
Inbound and outbound AI calling via Vapi and Twilio. ElevenLabs voice synthesis. Real-time STT/TTS. Lead qualification, appointment booking, 24/7 receptionist automation. GoHighLevel and HubSpot CRM sync.
Workflow Automation with AI Decision Layers
n8n agent workflows, Make scenarios, GoHighLevel pipeline automation. The difference from standard automation: every workflow has an LLM decision layer, not just if/then logic.
RAG and Document Intelligence
Semantic chunking, hybrid search, reranking with Pinecone and pgvector. GPT-4o vision for invoice and document extraction. Three-way matching, ERP sync (QuickBooks, Xero, SAP, NetSuite). AP automation with 98%+ accuracy.
Production Infrastructure
FastAPI backends, PostgreSQL and Supabase, Redis, Docker, Railway, AWS. Every system ships with monitoring, error handling, and documentation. Not a side project setup.
