Federico Tafur
AI/ML Engineer & Data Scientist

About Me
I’m an AI/ML Engineer & Data Scientist passionate about the intersection of computer science, finance, and data-driven systems. I love translating complex problems into elegant, production-ready solutions that create real-world meaning.
Recently, I built Chronos, an ML-driven trading algorithm focused on signal generation, risk-aware execution, and robust evaluation. Chronos combines feature engineering, modern model architectures, and careful validation to turn market structure into actionable strategies.
Beyond individual projects, I’m driven by entrepreneurship—bootstrapping products that feel revolutionary: useful, fast, and trustworthy. I enjoy the full stack of building from research to deployment: experiment design, modeling, API/product integration, and iteration with users.
Before tech, I pursued sports at an elite level: I played professional first-division soccer in Costa Rica and later moved to the United States to compete in NCAA Division I college soccer. That background shaped my commitment to discipline, teamwork, and performance under pressure—values I bring to every build.
