Hire the Best LangGraph Specialists

AI engineer. 29 jobs done on Upwork, $10K+ earned, 100% job success rate. What I mostly work on: → Agent systems. LangGraph, custom orchestration, MCP. Used for things like document analysis pipelines and internal company tools. → RAG. Pinecone or pgvector setups. Tuned for production, not just plug-and-play LangChain. → Full AI products. I've shipped paid marketplace apps and multi-agent backends. Real shipped products, not demos. Some recent work I'm proud of: Column Mate. A paid Monday marketplace app I built. Live on the Monday App Store (App ID 10601212). Pricing tiers from $0 to $300 a month. It has 4 features the leading competitor doesn't have, including the only AI Parse Updates feature on the whole marketplace. Auto Blog Automation. An n8n pipeline I built for a client. Cut their article production from about 4 hours per article to under 5 minutes. Publishes to 5 platforms automatically. Business Control Center. I migrated a flat-file JSON system to Postgres for a client. 9 migrations shipped. Dashboard reads under 100ms p95. My main stack: Python, Node.js, FastAPI, PostgreSQL, n8n, OpenAI, Claude, LangChain, LangGraph, MCP, Pinecone, Whisper, ElevenLabs. I'm bilingual, Arabic and English. I handle the full system: auth, billing, infra, all of it. Not just the AI parts. If you want a working system instead of a research notebook, send me what you're trying to build.

Hi, I'm Mehroz 👋 Send me your AI agent project and i'll come back within 4 hours with a loom video showing exactly how I'd build it. Thats my promise. If you shoot me a message or invitation, i'll send that loom back so we both know if we're a fit before you spend a dollar. A little more about me: I build AI agents for founders and teams who need something that actually works in production, not just a demo that breaks the moment a real user touches it. Most "AI agents" on Upwork are GPT wrappers held together with prompts and luck. I build the real thing using Claude, LangGraph, and proper backend engineering. Agents that remember context, recover from errors, call your tools, and don't quietly hallucinate into your customer workflows. I've shipped this kind of work for a regional super-app in Ecuador, a US insurance-tech client doing document intelligence, and a B2B wellness messaging platform. Different stacks, same standard. ▪ 25+ AI projects delivered ▪ 100% Job Success Score | Top Rated on Upwork ▪ Clients in the US, LATAM, and MENA ▪ Certified in LangChain (DeepLearning.AI) and MLOps (Google Cloud) ▪ I speak English, Urdu, Hindi, plus working Spanish and Arabic ▪ Most of my projects ship in weeks, not months If you want someone who shows up, ships clean code, and won't disappear on you halfway through — i'm your guy. 🔧 EXPERTISE: AI Agent Development | Claude | LangGraph | LangChain | RAG | MCP | FastAPI | Python | LLM | Multi-Agent Systems | Anthropic API | OpenAI API | Prompt Engineering | AI Integration | Agentic AI
