Turning data
into decisions.

I'm Lenny Breylareth, a first-year student at the London School of Economics studying Data Science. My work spans machine learning research, data engineering, and full-stack development alongside developing advanced financial models.

I'm particularly interested in deep learning, natural language processing, and applying statistical methods to real-world problems in economics and finance.

Outside of coursework, I am passionate about robotics, I build side projects, contribute to open-source tools, and explore the latest advances in AI research.
