AI Agent Architect, 60+ production AI systems shipped, 100 success rate on Upwork. I build agentic infrastructure that runs businesses, not chatbot wrappers, not Zapier flows, not MVPs that die in week three. Most AI builds break the same way: hallucinations, no evals, no guardrails, no observability, runaway token cost. I architect the version that survives a year in production. What I build - AI agents and multi agent systems (LangGraph, OpenAI Agents SDK, Claude Agent SDK, CrewAI, AutoGen) - Voice AI agents that handle inbound and outbound calls (Vapi, Retell AI, ElevenLabs, Deepgram, Twilio) - Production RAG and Agentic RAG (hybrid search, reranking, Pinecone, Qdrant, Supabase pgvector, Chroma) - MCP server development for tool calling and enterprise data access - AI SDRs that qualify leads, book meetings, run follow ups 24/7 - AI receptionists for 24/7 call handling, scheduling, transfers - Custom AI SaaS platforms end to end (Next.js 15, FastAPI, Supabase, Postgres) - n8n, Make, Zapier, Claude Scheduled, GoHighLevel automations connected to agent backends Models and infra OpenAI GPT-5 and GPT-4o, Anthropic Claude Sonnet 4.5 and Opus, Google Gemini pro, Llama, Mistral. AWS Bedrock, Azure AI Foundry, Google Vertex AI. OpenRouter, vLLM, Ollama. Docker, Kubernetes, serverless. Recent work Autonomous pen-testing agent, multi agent content platform, lead qualification & conversting agent, AI image and video generation tools, production mobile apps with LLM backends. Why my agents get adopted Strong engineering plus a Master's in Marketing Psychology. Most AI projects fail at adoption, not at code. I design agents users keep using, not clever tech that dies in UAT. How I work One 30 minute scoping call; written architecture doc before any code, weekly demos, clean handoff. I ship in 2 week sprints with a working prototype by day 3. Send a message with what you're building, your deadline, and the one thing currently blocking the system. I reply within a few hours.
