Labeling Experience

Algorithmic Trading System Developer (logic testing and automated risk validation)

Developed a modular system for automated risk checks within an algorithmic trading pipeline. Implemented circuit breaker logic to enforce strict risk parameters and prevent over-leveraging during volatile conditions. Wrote comprehensive unit tests to ensure logically consistent and zero-error execution under stress. • Validated system behavior against defined risk constraints • Tested edge cases during high-volatility periods • Ensured correctness using structured unit testing • Verified logical consistency of execution paths

Technical Data Evaluation & Logic Testing (AI model output evaluation and adversarial red-teaming)

Text

Evaluated AI model outputs for factual accuracy and instruction adherence. Detected and documented logical inconsistencies and hallucinations in generated code and prose. Performed adversarial testing to stress-test reasoning quality in high-stakes scenarios. • Reviewed prompts and responses for compliance with specified instructions • Assessed outputs for grounding and logical validity • Reported hallucination and inconsistency findings • Used adversarial approaches to probe failure modes
