Advanced Code AI Evaluator (Independent Contractor) - Independent Contractor

TextText

You worked remotely as an Independent Contractor delivering advanced code-related evaluation and reference-quality outputs. Your responsibilities focused on assessing and improving generated code responses by checking correctness, constraints, and safety alignment, then producing optimized rewrites suitable for fine-tuning workflows. The role required strong analytical reasoning, program correctness evaluation, and multi-turn prompt design skills.• Evaluated and ranked AI model responses using dimensions like execution accuracy, complexity constraints, and safety guidelines. • Crafted multi-turn technical prompts to stress-test LLM outputs and identify logical flaws, syntax errors, and hallucinations. • Refactored and rewrote low-quality outputs into optimal human-level reference answers for model improvement. • Maintained consistent high correctness and accuracy ratings through stringent peer-review quality checks.
