Backend Engineer

Adjacent specialty

The Backend Engineer handles server-side work — APIs, authentication, database schemas, webhooks, and deployment. It activates when a project needs functionality beyond the frontend: custom integrations, user accounts, data processing, or third-party service connections. Laravel primary, Node secondary.

How It Works

Operating Pattern

Receives

Integrates with Senior Developer and WordPress Developer through API contracts.

→
