Project details
Are you tired of your team wasting hours manually answering questions, handling documents, or doing repetitive tasks?
I’ll build a fully customized AI Agent using LangChain/LangGraph, designed specifically for your business. It can:
🔍 Answer Questions from PDFs, Policies, Contracts (RAG pipeline with OpenAI or Claude)
📊 Extract Data from Invoices or Forms using OCR + LayoutLM
🧠 Automate Multi-Step Workflows like "Book appointment + notify team + update calendar"
🎤 Transcribe Meetings and generate summaries (Whisper/NVIDIA NeMo)
💬 Deploy Chat Interface on your website, CRM, or Slack
Perfect for: Startups, Legal, HR, SaaS Teams, Consultants, Healthcare, EdTech, eCommerce
✅ What You’ll Get
You will receive:
✅ A custom-built LLM agent (RAG-based or Tool-using)
✅ Integrated LangChain/LangGraph logic
✅ Document handling + memory + feedback loops
✅ API & tool integrations (search, calendar, Slack, etc.)
✅ Deployment via Docker or serverless (your choice)
✅ Short Loom walkthrough + setup documentation

C4D Python Genius
Rehan was super helpful. He went above and beyond for my project. The work he did do was beneficial and helped me over come several bottlnecks. He's a good problem solver and worked beyond the budgeted time. He continued to power through despite the budgetary restrictions and helped me get a perfectly working script. Highly reccomended
