Engineering playbook
Guiding principles and checklists for fintech teams shipping software that must be secure and dependable.
This playbook is a pragmatic set of habits AurumWeave uses when building fintech systems. It emphasizes clarity in ownership, workflow safety, and operational readiness.
Explicit Workflows
Ensuring every state transition is traceable, testable, and aligns with business requirements.
Design for Failure
Treating retries, timeouts, and partial failures as normal operating conditions, not edge cases.
Security by Default
Implementing least privilege, separation of duties, and safe data handling as a core engineering practice.
Core Principles
The foundations of our engineering culture.
Contracts over Assumptions
Always validate inputs and define clear semantics for inter-service communication to avoid brittle dependencies.
Operate what you build
Engineering teams own the observability and production stability of their services, ensuring logging and metrics align to business outcomes.
Incremental Improvement
We prefer steady, validated progress over high-risk "big bang" releases, using feature flags and canary deployments.
