    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 externship taught agent engineering with n8n, emphasizing agent design, orchestration, and dashboarding. The work involved installing and configuring n8n, designing agent workflows, and connecting agents to data sources and outputs. Deliverables included a live dashboard driven by the constructed agents.

What I've accomplished

I authored detailed image-generation prompts and implemented prompt nodes for a moodboard agent, specifying composition, lighting, textures, and resolution and documenting expected output variability.

Project breakdown

The module required creating prompt nodes for a moodboard agent. I wrote two detailed, image-generation prompts specifying composition, lighting, textures, and resolution, and I reflected on expected output variability and visual goals.
