Built an end-to-end Business RAG Knowledge Assistant that enables users to retrieve relevant information from business documents and generate grounded, context-aware answers using an LLM. Implemented document processing, chunking, embeddings, vector search, retrieval, context handling, source references, and a backend API for reliable AI-powered knowledge retrieval.

AI Assistant Using Your Business Knowledge Base — RAG on Your Documents
THE PROBLEM
Q&A bots break down when knowledge lives in documents: a 100-page manual has no "questions" to match, it can't fit into a prompt, and generic chatbots hallucinate instead of admitting what they don't know.
THE SOLUTION
A RAG (Retrieval-Augmented Generation) knowledge base: documents are split into meaningful chunks, embedded into a vector index, and the assistant answers from the right sections — by meaning, not keywords.
Any format as-is: PDF, DOCX, TXT, Markdown — 100+ pages is fine
Answers grounded in YOUR documents — it says "I don't have that information" rather than inventing
Source references — every answer shows which document and section it came from
Runs on your infrastructure — documents never leave your control
One command to re-index after updating documents — documented, no programmer needed
LIVE DEMO
Ask it about my products, pricing, deployment and support — it answers from 6 real documents with sources:

The 'I don't have that information' line is the part most RAG builds skip, and it's the one that matters. How do you set the cutoff? On mine, a fixed similarity threshold broke once I filtered results by user role. Scores shifted and it refused questions it could answer.
Built a digital presence for Associated Engineers & Builders
I wanted this website to feel like an extension of the company itself. Organized, clear and made to last. The visual style takes ideas from blueprints engineering charts and technical papers while keeping everything simple and up to date.
I designed and developed the website around their 30+ years of work, bringing together their services, projects, history, and company story into one responsive experience.The aim was straightforward: change a construction company into a powerful modern online presence without losing its engineering roots.
Built from beginning to end. Concept, design, development and launch.
What do you think of the style😍 ?
