MCP servers connecting AI Agents to live business systems. Evals, regression tests, LLMOps so the AI Agent holds up under real traffic. ▸ RAG Developer — Enterprise RAG & GraphRAG Pipelines RAG design, vector DB config (Pinecone, Weaviate, FAISS, ChromaDB), embeddings, chunking, reranking, citation grounding. GraphRAG on Neo4j. Multimodal RAG with OCR. ▸ Claude Code & AI Dev Tooling AI Developer using Claude Code + MCP for engineering workflows — scoped CLAUDE.md, sandbox-branch rollout, test-gated merges. Also Cursor, Windsurf, Bolt for AI-assisted development. AI Automation across Claude Code and MCP servers. ▸ AI Assistant Development — Chatbots, Copilots & Conversational AI AI Assistant Developer building AI Chatbots, AI Copilots, Conversational AI on Claude, OpenAI, Gemini, open-source LLMs. RAG document Q&A, Microsoft Copilot integrations. Cuts tier-1 tickets 70-80%. ▸ AI Automation & AI Integration — n8n, Claude Code, MCP & APIs Connecting AI Agents to CRM, ERP, SaaS, databases via REST API, webhooks, LangChain, MCP, n8n, Zapier, Make. ▸ AI Voice Agent Development AI Voice Agents on LiveKit, VAPI, Twilio — tool-calling, appointment booking, latency tuning, production evals. ▸ LLM Fine-Tuning Fine-tuning Llama, Qwen, Phi, DeepSeek with LoRA/QLoRA for domain-specific AI Agent behavior. Eval harness, adapter hot-swap. ▸ AI Engineer & Fractional AI Consultant — Architecture & Advisory AI Agent roadmap, architecture review, LLM/RAG stack selection, build-vs-buy scoping. ━━━━━━━━━━━━━━━━━━━━━ WHO I WORK WITH 🎯 SaaS and enterprise teams building AI Agents, AI Assistants, AI Automation — not one-off pilots 🎯 Fintech, healthcare, manufacturing, regulated verticals with real data and real stakes 🎯 Funded startups moving an AI Agent MVP into production 🎯 Clients on retainer or T&M who value senior AI Agent Developer judgment ━━━━━━━━━━━━━━━━━━━━━ MY PROCESS 1️⃣ Discovery — your AI Agent or RAG use case, current stack, production needs 2️⃣ Architecture proposal — AI Agent flow, tool boundaries, fallback, eval plan, delivered in a week 3️⃣ Build and ship — production-grade AI Agent with evals, regression tests, LLMOps 4️⃣ Handoff or stay — train your team, or stay on as Fractional AI Consultant ━━━━━━━━━━━━━━━━━━━━━ DELIVERY NUMBERS 75% avg reduction in manual ops · 3x faster feature shipping · 80% tier-1 support automated by AI Assistants ━━━━━━━━━━━━━━━━━━━━━ CORE TECH STACK LLMs: OpenAI (GPT-4o, o1), Claude, Gemini, Llama, Qwen 2.5, DeepSeek, Mistral, Whisper, LoRA/QLoRA AI Agents: LangChain, LangGraph, LlamaIndex, AutoGen, CrewAI, SmolAgents, MCP, Multi-Agent, Agentic AI AI Dev Tools: Claude Code, Cursor, Windsurf, Bolt, MCP servers RAG: Pinecone, Weaviate, FAISS, ChromaDB, Neo4j, GraphRAG, LightRAG, Embeddings, Reranking Voice: LiveKit, VAPI, Twilio, WebRTC, Deepgram, ElevenLabs, PaddleOCR LLMOps: FastAPI, LangSmith, Langfuse, evals, observability, guardrails, prompt versioning AI Automation: n8n, Zapier, Make, REST API, webhooks, Microsoft Copilot, GitHub Actions Full Stack: Python, TypeScript, React, Node.js, .NET, PostgreSQL, MongoDB, AWS/GCP/Azure ━━━━━━━━━━━━━━━━━━━━━ INDUSTRIES Manufacturing | Construction | SaaS | Fintech | Healthcare | E-commerce | Real Estate | HR Tech 📩 Send me your current workflow.
