Crawleo is a comprehensive SaaS solution built to solve the 'knowledge cutoff' problem for AI models. Beyond the core crawling engine, the true engineering feat lies in its backend architecture.

I designed a system that handles high-concurrency API requests with a strict zero-data retention policy while managing a complex financial lifecycle. The project implements the Model Context Protocol (MCP) to allow direct integration with AI agents like Claude and Cursor.

The backend is a testament to Clean Architecture, featuring a highly scalable, event-driven system that handles subscription states, metered billing, and real-time webhooks with absolute precision.
