AI-Powered Enterprise Knowledge Assistant
Architected an internal AI-powered knowledge assistant for StackDot teams, implementing a RAG pipeline with controlled ingestion, source-backed context answering, and an anti-hallucination validation layer to eliminate operational and technical query bottlenecks.
Executive Summary
Goal
Build an internal AI-powered knowledge assistant (K-Assist) for StackDot teams to reduce human dependency for operational, HR, and technical queries while maintaining zero hallucination rates.
Solution
Developed a vector-search RAG pipeline with controlled document ingestion, context-aware source-cited answering, role-based access control, and a rigorous response validation layer.
Outcome
Reduced internal support ticket volume by 65%, eliminated repetitive team interruptions, and provided instant 24/7 access to accurate internal documentation.
Strategic Value
Created a scalable internal AI blueprint that accelerates onboarding, standardizes company knowledge, and serves as an enterprise RAG demonstration for client engagements.
Business Challenge
Company information and technical docs fragmented across multiple tools, repositories, and PDFs.
Repetitive internal operational, HR, and technical queries continuously interrupting senior engineering and ops teams.
High risk of AI hallucinations or outdated answers when retrieving complex technical & policy guidance.
Project Objectives
Active Industry
Ingestion
StackDot Approach
Multi-Source Document Pipeline
Configured automated extractors for Notion, GitHub markdown, Slack archives, and internal PDF policies.
Vector DB & RAG Architecture
Built a hybrid vector search (Pinecone / Pgvector) with Semantic Chunking and dense embeddings.
Anti-Hallucination Validation Layer
Implemented strict confidence thresholding, source citation verification, and fallback routing.
Role-Based Access Deployment
Integrated Okta/OAuth SSO with role-filtered vector search for internal team rollout.
Solution Highlights
Information spread across multiple documents & tools → Structured knowledge base with controlled ingestion.
Repetitive internal queries slowing teams → Context + source-based response generation.
Risk of incorrect or outdated responses → Validation layer to prevent hallucinated answers.
