Building a Personal Q&A Chatbot on AWS using Bedrock Nova Pro

I built a Personal Q&A Chatbot on AWS that can answer questions about me using my stored profile data and a powerful foundation model from Amazon Bedrock. This project is a great example of combining serverless architecture with Generative AI.

Architecture Overview

The chatbot follows a simple and scalable request-response flow:

• User asks a question through the chat interface
• The request is received by Amazon API Gateway
• API Gateway triggers an AWS Lambda function
• Lambda fetches relevant personal context from Amazon S3
• Lambda sends the prompt + context to Amazon Bedrock (Nova Pro)
• Bedrock generates a smart response and returns it back to Lambda
• The response is sent back to the user via API Gateway

Key AWS Services Used

• Amazon API Gateway – Handles incoming and outgoing chatbot requests
• AWS Lambda – Core backend logic and orchestration
• Amazon S3 – Stores profile documents and personal data
• Amazon Bedrock Nova Pro – Generates accurate AI-powered answers

Why This Approach Works

This architecture is fully serverless, scalable, and cost-efficient. By combining personal context from S3 with Bedrock’s Nova Pro model, the chatbot can deliver meaningful and personalized responses instantly.
