How our engineering connects together
Whether delivering an internal tool or a multi-tenant platform, we separate concerns across each layer of the operational stack.
Static architecture overview.
User interface
What people see and touch, built to work on any screen and with a keyboard.
Application layer
Routing, state and rendering that turn data into screens.
Authentication
Who is allowed in, and what each person may do.
API
The contract between the interface and the systems behind it.
Business logic
The rules specific to the product, kept in one place.
Database
Where data lives, shaped to match how the product uses it.
Infrastructure
Hosting, deployments, environments and monitoring.
External integrations
Payments, email and other services, connected through the API.
