I'm a software engineer focused on building reliable, deterministic real-time and trading systems. My work spans system design, implementation, deployment, and production operations, with an emphasis on correctness, observability, performance stability, and failure-aware architecture.

I'm particularly interested in probability, statistics, machine learning, and fault-tolerant distributed systems, and in how financial markets behave as high-dimensional, non-stationary systems whose structure evolves over time. Rather than "solving" markets, I focus on building robust systems for exploring, testing, and operating within them.

This site documents my projects, experiments, and technical notes on trading, systems engineering, and quantitative research.
