QUANTITATIVE RESEARCH · TRADING · MODEL VALIDATION

I turn market questions into testable, auditable research.

I build and test market models in Python, with explicit controls for bias, leakage, transaction costs, and out-of-sample performance.

Equity Volatility Research Pipeline

An end-to-end investigation that moved from return construction and strategy backtesting to volatility diagnostics and leakage-aware forecasting.

OUT-OF-SAMPLE RESULT

HAR remained strongest after purged validation.

Purging 21 boundary observations raised HAR RMSE from 9.03% to 9.08%. The lower unpurged figure is preserved as a diagnostic; the corrected result is the headline.

Lagging the trading position by one day removed information that was unavailable at execution time.

ROBUSTNESS0 of 4

The net SMA strategy beat buy-and-hold on none of the four equities tested—an informative null result.

TARGET DESIGNRanking reversed

Changing only the evaluation target reversed the apparent forecast ranking and exposed a misleading overlap.

02 / PROFESSIONAL DATA EXPERIENCE

Production data controls across 60,000+ accounts.

At Bright Power, I built SQL and ETL workflows, reconciled records across five systems, and resolved more than 390 data-integrity exceptions. The work reduced manual handling by approximately 75% and prevented $20,000–$30,000 in recurring vendor costs.
