What this actually is

You review AI-generated code, rank model outputs against each other, write prompts that test edge cases, and provide expert feedback that gets used to train coding models. Not shipping production software. The platform title (Backend Engineer Talent Network) reflects the rate band and the expertise required, not the day-to-day work.
