03 / APPLICATION INFRASTRUCTURE
The logic behind the interface.
I implement backends and integrations for web applications, including REST APIs, authentication, role-based access and Stripe billing workflows. I map the business rules before writing endpoints, keep credentials on the server and test important success and failure paths. The implementation and handover are scoped to your existing stack and deployment environment.
Backend, APIs, auth and billing
APIs, authentication, RBAC and Stripe integrations designed around your application’s actual rules. I work directly with your team to define the deliverables, understand your existing systems and build changes that can be reviewed. The exact implementation, schedule and acceptance criteria are agreed before the work starts.
What the scope can include
- Documented API contracts and data relationships
- Authentication and server-enforced access controls
- Stripe integration with webhook verification and retry handling
- Validation, integration tests and operational handover
What we’ll clarify first
- What application rules must hold on the server?
- Which external systems and payment flows are involved?
- Who maintains the backend after the build?
