SUMMARY:Stop Guessing: Build Feedback Loop for Prompt Engineering - Tadas

DESCRIPTION:Most teams iterate on prompts by eyeballing outputs and hoping
  for the best. This talk presents a different approach: connect your promp
 t to a measurable downstream outcome\, build a test set\, and let metrics 
 drive improvements. I'll walk through a complete feedback loop - from prom
 pt to retrieval metrics to automated error analysis to LLM-powered iterati
 on - and show how this turns prompt engineering from guesswork into someth
 ing you can actually measure and improve systematically.
