Project details
Build intelligent AI chatbots that don’t just reply—they understand, retrieve, and solve.
I’m an AI developer specializing in **RAG-powered chatbots, OpenAI, LangChain, and vector database systems** that turn your data into a smart, conversational assistant.
From customer support bots to SaaS AI assistants, I build scalable solutions that combine **LLMs + retrieval systems + clean UI/UX** for real-world performance.
**What I build:**
• AI Chatbots with RAG (your data + real answers)
• OpenAI / GPT-powered assistants
• LangChain-based agent workflows
• Vector DB integration (Pinecone, Chroma, FAISS, etc.)
• Document, PDF, and knowledge-base chat systems
• Next.js / Streamlit frontend integration
• FastAPI / Node.js backend systems
Every solution is designed for **accuracy, scalability, and real business use—not just demos**.
Perfect for startups, SaaS products, and businesses that want to automate support, improve user experience, and unlock their data with AI.
Let’s turn your data into a powerful AI assistant that actually works in production.
