You will get AI RAG Chatbot: Custom Knowledge Base Q&A System


Project details
I build AI chatbots that answer questions using YOUR documents - no hallucinations, just accurate answers grounded in your data.
WHAT YOU GET:
• RAG-Powered Chatbot - Your chatbot retrieves relevant information from your documents before generating responses. This means accurate, context-aware answers every time.
• GPT-4o / Claude Integration - Uses the latest AI models for natural, helpful responses that understand context and nuance.
• Vector Database Setup - Your documents are indexed with semantic embeddings for fast, relevant retrieval. Works with PDFs, TXT, Markdown, DOCX, or web content.
• Production-Ready API- Clean REST API endpoint you can integrate into your website, app, or internal tools.
• Demo Interface Included - Test your chatbot immediately with a working demo UI.
PERFECT FOR:
• Customer support automation
• Internal knowledge bases
• Product documentation Q&A
• FAQ chatbots
• Training material assistants
• Legal/compliance document search
I have built production RAG systems handling 1000+ daily queries with 95%+ accuracy. Clean code, full documentation, and deployment support included.

About Gaurav
AI/ML Engineer & Full Stack Developer | RAG | GPT Integration | Mobile
Noida, India - 9:18 pm local time
What I bring to your project:
Full Stack Development -> End-to-end product development with React Native (Expo), React, NodeJS/Express, FastAPI, and MongoDB. I architect scalable systems that handle real users and real traffic.
AI Engineering & LLM Integration -> Hands-on experience building production AI pipelines with GPT-5, computer vision, OCR, and multimodal processing. I design prompt systems that deliver consistent, high-quality results.
RAG (Retrieval Augmented Generation) -> Custom RAG implementations for domain-specific AI assistants, including vector stores, semantic search, and context-aware response generation.
Mobile App Development -> Native-quality cross-platform apps using React Native & Expo SDK 54, with in-app purchases (iOS & Android), deep linking, and offline-first architecture.
Cloud & DevOps -> AWS (Elastic Beanstalk, S3, ElastiCache), Docker, Redis, real-time streaming (SSE), and production monitoring with Sentry.
Recent project highlights:
- Built an AI-powered video analysis platform processing thousands of videos monthly with GPT vision models
- Developed a real-time product extraction pipeline with parallel detection, deduplication, and affiliate integration
- Created a multi-region mobile app with subscription billing, device-based auth, and quota management
- Implemented production RAG systems for AI assistants with custom knowledge bases
- I write clean, maintainable code with proper error handling, security best practices, and comprehensive documentation. Let's build something great together.
Completed Projects -
1. AI-Powered Video Analysis Platform - Built a full-stack mobile application that uses GPT vision models to analyze video content in real-time. The system processes videos from multiple social platforms, extracts meaningful data using computer vision and OCR, deduplicates results using AI, and presents actionable insights to users.
Tech -> React Native, Expo, FastAPI, Python, GPT-4/5, OpenAI Vision API, MongoDB, Redis, AWS
2. Production RAG System for AI Assistant - Designed and implemented a Retrieval Augmented Generation system that powers an intelligent assistant. Features include custom knowledge base management, semantic search, context-aware responses, and streaming output for real-time interaction.
Tech -> Python, FastAPI, OpenAI API, Vector Embeddings, Redis, SSE Streaming
3. Multi-Region Subscription Mobile App - Developed a cross-platform mobile app with complex subscription management supporting multiple regions and currencies. Implemented device-based authentication, in-app purchases for iOS and Android, quota management with timezone-aware calculations, and real-time WebHook processing for subscription events.
Tech -> React Native, Expo SDK 54, NodeJS, Express, MongoDB, Apple StoreKit, Google Play Billing
4. Real-Time Data Processing Pipeline - Architected a scalable async job processing system with SSE-based progress streaming, circuit breakers for external API resilience, distributed locking, and parallel processing workers. Handles thousands of requests daily with 99.9% uptime.
Tech -> FastAPI, Python asyncio, Redis, Docker, AWS Elastic Beanstalk
