You will get an AI Knowledge Base With RAG Document Q&A


Project details
Turn your company documents into an AI-powered Q&A assistant that gives instant, accurate answers with source citations.
No more searching through hundreds of pages. Your team or customers upload documents and ask questions in natural language — the AI reads, understands, and answers from your actual data.
How it works:
Documents are parsed and split into searchable chunks. When a question comes in, the system finds the most relevant sections and sends them to the AI along with the question. The AI generates a precise answer and shows exactly which parts of the document it used.
Use cases:
• Employee onboarding knowledge base
• Customer self-service from product documentation
• Legal document analysis and clause extraction
• Research paper summarization and Q&A
• Internal policy and compliance assistant
Tech stack: Next.js 15, TypeScript, Python, LLM APIs (OpenAI/Claude/DeepSeek), vector search, PostgreSQL, Tailwind CSS.
I've built and deployed a working RAG system — see my portfolio for a live demo. Every delivery includes full source code, documentation, and deployment to your domain.

About Kelvin
AI Integration & Full-Stack Developer | Chatbots, RAG Systems, API
Manchester, United Kingdom - 4:09 am local time
What I deliver:
→ AI chatbots & virtual assistants (Next.js + OpenAI/Claude/DeepSeek API)
→ RAG document Q&A systems with vector search & source citations
→ AI agent development & multi-step workflow automation
→ AI integration into existing SaaS platforms & legacy systems
→ Automated data pipelines & real-time processing systems
→ API integrations connecting multiple services (CRM, Slack, email, databases)
→ Full-stack web applications with AI features built in
→ n8n / Zapier / Make automation workflows with AI
My background is in building real-time systems that handle live data. I've independently designed and deployed automated bots that process market data from multiple API sources (REST + WebSocket), execute decisions based on custom logic, and run 24/7 on VPS infrastructure. This means I understand production reliability — not just getting code to work, but keeping it running.
Tech stack: Next.js, React, TypeScript, Node.js, Python, FastAPI, LangChain, PostgreSQL, Supabase, Pinecone, OpenAI API, Claude API, DeepSeek API, Vercel AI SDK, WebSocket, Docker, Linux/VPS deployment.
I respond fast, deliver faster, and write clean code with documentation.
