How I Built ProjectHub: An Embeddable AI Recruiter Assistant That Runs on Free Tiers

I built a chat widget for my portfolio. One script tag, drop it on a page, and recruiters can ask questions about my projects, my AWS internship, what I actually know, and what kind of roles I'm looking for. I named the assistant Scout.

That's the whole pitch from the outside. What it took to get there is a lot messier than one script tag suggests. The current version has a vanilla JS frontend, a Node backend on a Google Cloud e2-micro VM, a knowledge base pulled from GitHub, a network of free LLM providers, a response cache, per-tab memory, safety checks, a self-improvement loop, and an analytics dashboard. It also has six test suites and more documentation than I expected.
