# Apps

> Authenticated products, domain logic, permissions, APIs, and account lifecycle flows. Quoia builds applications that survive real users and real data.

Canonical page: https://quoia.dev/services/apps

Applications are where business rules become software. Quoia builds authenticated products with explicit domain boundaries, real identity and access control, and integration surfaces that other systems can depend on.

## Capabilities

- Product architecture - module boundaries, state ownership, and data flow that survive feature growth.
- Identity and access - authentication, roles, permissions, and account lifecycle handled once and correctly.
- Domain logic - business rules expressed in code that can be read, tested, and changed safely.
- Integration boundaries - APIs and contracts that let the rest of the stack build on the product.
