About

My work sits at the intersection of:

  • Probability & Statistics
  • Game Theory & Market Microstructure
  • Implied Volatility & Derivatives
  • Machine Learning (as a tool, not a crutch)
  • LLM Research on Time Series Embeddings

I care deeply about how decisions are made — not just whether a model predicts well — and I enjoy building systems that make those decisions visible, testable, and improvable.


Current Focus

  • Volatility surface trading

    • OTM-only IV dislocation strategies
    • Surface-level reasoning rather than point estimates
    • Portfolio-level risk (delta / vega) over single-trade PnL
  • LLM Research on Time Series Embeddings

    • LLMs excel at language but are not designed for numerical sequences.
    • Time-series data is ubiquitous, appearing in sensors, finance, EEG, climate, etc.
    • Effective numerical embeddings are needed as a "translation layer."

Background & Interests

  • Strong Mental Arithmetic
  • Quantitative trading & market making
  • Options theory and volatility modelling
  • Game-theoretic thinking
  • Applied probability

Built with curiosity, restraint, and a long-term view.
