I built an AI-powered system that automatically detects undervalued iPhones listed on eBay and notifies users in real time. The app uses GPT to analyze item descriptions and integrates predefined pricing rules to identify potentially undervalued listings. It sends push notifications via Pushover when a match is found.

To make this work, I used the eBay API to search and filter listings, AWS Lambda for serverless execution every 5 minutes, and OpenAI's GPT to analyze item conditions. GitHub Actions and AWS tools were utilized for continuous integration and deployment, ensuring the Lambda function stays updated with the latest code.

This project was a great way to integrate cloud services, APIs, and AI to create an automated system for real-time market monitoring.
