About

I build proprietary HFT market-making systems at the intersection of market microstructure research and low-latency systems engineering. My public research program focuses on Event-Semantic Limit Order Books: representing market dynamics through event structure, projection loss, microstructure signals, and queue-aware execution. My private engineering work spans market data ingestion, order book reconstruction, strategy evaluation, execution gateways, risk controls, telemetry, and low-latency infrastructure. Public materials are intentionally limited to non-proprietary research and sanitized systems architecture.

Private HFT Market-Making Stack active

A proprietary trading systems codebase covering market data, order book reconstruction, strategy evaluation, execution, risk controls, observability, and low-latency infrastructure. Details are intentionally limited due to proprietary trading confidentiality.
