Secure Data Handling

The Challenge

The client’s existing chatbot could only handle simple quantitative inputs with limited reasoning capability, lacking scalability and contextual understanding, while failing to deliver consistent accuracy for handwritten or image-based questions. Key challenges included the inability to interpret mathematical reasoning, generate detailed steps, or provide contextual learning and session management. The client required an AI-native solution capable of multimodal input processing, explainable reasoning, seamless LMS integration, and maintaining security with cost efficiency.

Solutions

• Amazon API Gateway serves as the entry point for all chatbot queries
• AWS Lambda provides core compute layer that invokes Amazon Bedrock for reasoning, manages orchestration, and formats responses
• Amazon Bedrock (Claude Sonnet 4) delivers step-by-step AI reasoning and LaTeX-based solutions
• Amazon S3 securely stores image-based math questions via pre-signed URLs
• Amazon DynamoDB maintains chat history, session metadata, and user feedback
• AWS IAM, Amazon CloudWatch, AWS CloudTrail handle access control, observability, and compliance

The Results

Achieved 94% accuracy boost, 60% faster processing, zero manual scaling, 100% secure data handling, and enhanced student engagement through detailed step-by-step reasoning.
