Labeling Experience

Financial Domain Expert & Derivatives Logic Evaluation

TextRLHF

Applying 9 years of domain expertise in the Hong Kong warrant and global derivatives markets to evaluate AI-generated financial analysis. I specialize in identifying logical fallacies in market predictions, verifying the accuracy of complex financial calculations, and ensuring model outputs align with real-world trading mechanics. My focus is on Reinforcement Learning from Human Feedback (RLHF) to improve the "reasoning" capabilities of LLMs when handling high-volatility financial data and risk management scenarios.
