About Me

I work at the intersection of quantitative research, machine learning, and software engineering, with a strong focus on financial time series, statistical modeling, and decision-making under uncertainty.

My background is in building and experimenting with models for market behavior, portfolio optimization, risk estimation, and signal research. I enjoy starting from raw data, forming hypotheses, designing experiments, and iterating on models until they either fail clearly or reveal something useful.

I place a strong emphasis on understanding why a model works or breaks, rather than optimizing blindly. Most of my work involves Python-based research pipelines, statistical analysis, feature engineering, and translating research insights into reliable systems.

I am particularly interested in quantitative trading, market microstructure, regime detection, and the application of statistical and ML techniques to real-world financial problems.
