What I'm looking for

I seek roles where I can design data-driven trading or analytics systems, work cross-functionally, apply rigorous research, and grow in quantitative and engineering responsibilities.

I am a quantitative researcher and data scientist with strong experience building predictive trading models, ETL pipelines, and backtesting systems. I have delivered production-ready data engineering solutions, implemented data governance practices, and translated complex analyses into actionable insights across finance and health domains.

My background spans Python-driven quantitative research, SQL/NoSQL database design, microservices and trading infrastructure, and visualization tools that improve decision-making. I collaborate effectively across teams and have a proven track record of improving trading outcomes and product metrics through rigorous research and robust engineering.
