INFIN8: AI Agent Marketplace for Creator Advertising

This project involved building the AI layer of INFIN8, a live marketplace where brands buy standardized creator ad deliverables at clear prices and creators get a media kit and rate card.

The platform was built with NestJS and Next.js, with LangGraph powering the AI agents.

A LangGraph onboarding agent extracts creator details using LLM slot resolution instead of regex, making onboarding more flexible and reliable.

Tool-calling chat agents let brands create campaigns and send offers, and let creators query their own analytics through conversation.

AI pricing suggestions are generated from audience data, and a media-kit PDF parser turns uploaded media kits into structured creator information.

Content validation is handled with Gemini, running on Bull queues with Google Cloud Storage for background processing and file handling.

I also migrated social account connection from Phyllo to Ayrshare.

The platform is in production at infin8.media.
