Quant Systems & Trading Architecture

Trading system architecture
and decision logic.

What I do

Decision Architecture

How trading systems form decisions, where assumptions fail, and how risk and execution behave under real market conditions.

Risk & Capital Design

Construction of risk logic, capital allocation, and volatility-aware decision layers that govern system behavior.

System Survivability

Defining when systems trade, pause, scale, or stop — under stress, regime shifts, and execution constraints.

How I work

  1. Define the decision boundaries
  2. What the system is allowed to do - and more importantly, what it must never do.

  3. Stress decisions under real constraints
  4. Testing assumptions against volatility, liquidity, regime shifts, and execution friction.

  5. Design risk and capital behavior
  6. Structuring how risk expands, contracts, or disengages as conditions change.

  7. Establish survivability rules
  8. Defining when systems trade, pause, scale, or shut down - without discretion.
