What I'm looking for

I’m looking for a role that unites investment analysis with AI/ML—where I can build data-driven research, strengthen decision-making, and contribute to LLM/AI training while maintaining rigorous risk management and real-world market impact.

I’m a dynamic CFA Charterholder and Economist with 20 years of expertise in financial analysis, equity research, and investment management. I combine deep capital markets acumen with emerging AI/ML capabilities to turn complex data into actionable insight.

Recently, I expanded into AI and machine learning work, developing cutting-edge training datasets for large language models and contributing to reinforcement learning from human feedback (RLHF). I also create benchmarking data to evaluate and advance model performance specifically for finance domains.

Alongside AI, I’ve built a proven record across portfolio and research roles—from delivering investment recommendations using DCF and comparable analysis to running proprietary algorithmic and discretionary futures strategies. I’m passionate about leveraging technology and advanced analytics to improve how investment decisions are made, backed by rigorous risk management and client-focused advisory.
