    Wayfair n8n AI Agent Engineering Externship

    Learn one of the most in-demand skills shaping the future of work: building AI agents. In this externship, you’ll step into the role of an AI Agent Developer and use n8n to design agents that think, plan, and act on real data — automating insights, decisions, and workflows. No coding experience required. By the end, you’ll create a live dashboard powered by your own AI agents, gaining hands-on experience that applies to any role or industry — from marketing and consulting to product management and data science.

Overview

The work prototyped an end-to-end document intelligence pipeline for pharmaceutical SDFs, combining OCR, layout-aware extraction, chunking, embeddings, vector search, reranking, and a Gradio chatbot front end. Deliverables included OCR comparisons, Python extraction scripts that exported JSON, multiple RAG configurations with logged retrievals, and a Colab repo plus slide deck with evaluation

Overview

The externship trained participants to build AI agents that plan and act on data using n8n. The work configured n8n flows, connected external data sources, and assembled agent logic into an interactive dashboard. The deliverables included a live dashboard driven by the constructed agents.

What I've accomplished

I built and validated a Moodboard Generator prompt set: I wrote sample prompts, recorded the system prompt, and verified that chatbot responses produced on-topic, detailed design concepts.

Project breakdown

During the Build Your First Prompt Node task I wrote and tested prompts (French country with a Persian rug; a prairie-style den with coffered ceiling and zebra rug), recorded the system prompt used, and reflected on the chatbot responses, which stayed on-topic and detailed design concepts.
