Reaper — Agentic Web Data Platform

Built Reaper, a website-to-API platform that uses a browser agent to crawl dynamic web pages, examine network activity, and infer which XHR/fetch requests return the underlying structured data. Designed the extraction pipeline to replay validated source requests directly as reusable REST endpoints, reducing reliance on brittle DOM parsing, headless browser sessions, and slow page-render workflows.
