What I'm looking for

I’m looking for a remote role where I can build end-to-end market data pipelines and systematic trading infrastructure—Bronze/Silver/Gold style ETL, robust validation, and automated execution systems with controlled risk.

I’m a Financial Data Engineer with 8+ years building proprietary market data infrastructure from the ground up. I designed and operate a fully automated trading OS at Quintero Capital that processes 5,820+ tickers weekly through a Bronze/Silver/Gold medallion pipeline with a Dead Letter Queue and incremental loading.

I develop and validate systematic strategies across equities, futures, FX, and commodities—100+ strategies with 50%+ achieving positive out-of-sample results. My live performance includes +8% net return in 2025 and +20% YTD in 2026, supported by controlled risk and no discretionary overrides, plus ongoing out-of-sample and robustness testing.
