Architecture with clear boundaries
Identify who owns each system and data contract. Record important decisions, their constraints and when to revisit them.
Engineering / How we work
Sound engineering leaves a trail people can use. We connect decisions, checks and operational evidence so teams can change systems with confidence.
Engineering principles
Identify who owns each system and data contract. Record important decisions, their constraints and when to revisit them.
Define trust boundaries and access needs early. Review dependencies, avoid secrets in source and test the failure behavior that matters.
Use lower-level checks for rules and contract coverage. Keep end-to-end checks focused on important journeys and preserve enough context to reproduce failures.
Review generated changes with the same scrutiny as other changes. Evaluate AI-enabled features against representative inputs, including uncertain outputs and fallback behavior.
Prefer explicit interfaces, repeatable builds and understandable code. Document operating procedures and the decisions teams need to carry forward.
Observe release outcomes and recurring failure patterns. Use the findings to improve tests, operational visibility and the next increment of the product.
