Data engineer · Santo Domingo, Dominican Republic · open to remote roles
I build data pipelines that hold up outside a notebook: real sources, point-in-time correctness, tests and CI. MSc in Data Science & Business Analytics, currently studying Software Engineering to pair the data side with solid engineering practice.
Equity screener for the S&P 500 + NASDAQ 100 built on a strict point-in-time pipeline: fundamentals enter by their real SEC filing date, macro series by their ALFRED vintage, and 8-K sentiment only from the next business day — so the backtest can't learn from the future. Trained on 298k rows (515 tickers, 34 features), with SHAP explanations per signal, a rule-based exit engine and graduated drift monitoring.
