HOW WE APPROACH IT
Agree ownership of each field and event. Test duplicate, delayed and malformed messages as well as the successful request, with sensitive values excluded from logs.
Our delivery processTECHNOLOGY
REST APIs, Node.js, Express and PostgreSQL.
Architecture choices follow requirements, maintainability and operational constraints.
Technology choicesQUESTIONS BEFORE WE START
The design can include bounded retries, queues, user-visible states and reconciliation. The appropriate strategy depends on whether the operation can be repeated safely.
We review the scope, integrations, content and delivery constraints first. The proposal records assumptions, milestones and exclusions; changes are assessed against that baseline.
