BUILD

Engineer the frontend, backend, integrations and data layer. The build stage turns approved decisions into a working, testable system using reusable code, clear architecture and controlled delivery.

QUALITY FIRST

Engineering principles

Build reusable components instead of one-off sections.
Keep logic separated from presentation where practical.
Validate data at system boundaries.
Handle empty, loading, success and error states.
Keep production configuration outside source code.

Definition of done

Feature matches approved behavior.
Responsive layout works at required breakpoints.
Critical flows have graceful failure states.
Code is readable and maintainable.
Feature is ready for QA, not just visually complete.
