How I build systems

Clarify the risk model

Define failure modes early, align stakeholders on tradeoffs, and codify policy into system design.

Design for traceability

Every action produces a durable audit trail, making compliance and debugging part of the system.

Ship with guardrails

Progressive rollouts, automated tests, and monitoring ensure reliability without slowing teams.
