About

I build end-to-end quantitative research pipelines: from raw market and macro data through feature engineering, rolling out-of-sample model evaluation, and portfolio-level analysis. My work emphasizes reproducible backtests, explicit risk overlays, and communication of methodology — not black-box performance claims.

Currently focused on multi-timeframe FX directional forecasting (daily through intraday), expanded-universe backtests, and integrated research dashboards for signal monitoring and production workflows.

Research principles

  • Out-of-sample evaluation first — rolling holdout and walk-forward protocols, not in-sample fit.
  • Transparent data lineage — versioned parquet pipelines, manifest reports, reproducible run scripts.
  • Risk-aware framing — stop-loss overlays, transaction-cost sensitivity, and clear limitation statements.

Selected research

US sector allocation by rate, inflation & business cycle

Long-history study of which US equity industries outperform under different macro regimes, using Ken French 12 industry portfolios with Shiller long rates, headline CPI, and industrial production. Maps conditional sector returns across rate direction, inflation level, and business-cycle phase.
