Eric does things.

Human in the loop. AI in the driver's seat. Me with the emergency brake.

Hi, I'm Eric Yim. Everything here is a joint venture between me and an AI.

The workflow is simple: the AI spews fast, remarkably confident nonsense; I catch it red-handed, fix the citations it completely made up, and sign off before anything hits production.

To sum it up: It brings the typing speed. I bring the adult supervision.

If you spot a bug or a hallucination wearing a tuxedo, that's on me โ€” the AI tried its best to gaslight me, and I fell for it.
