One backend module with up to three endpoints, input validation, agreed access rules, data handling and tests within an existing application. A complete backend or new infrastructure is quoted separately.

Estimated delivery starts at 7 calendar days for this package, from our agreed start date once access and required materials are ready. The starting price and timeline are negotiable and depend on your brief, requirements, existing code and input quality. We confirm the scope, price and schedule before work begins. Additional scope, third-party subscriptions, API usage, hosting and ongoing support are quoted separately.

Build the server-side operations your application needs. I implement APIs, business rules, data access, and external connections around a defined product requirement.

The agreed endpoints, server operations, and supporting data changes.

Input validation, access checks, and error handling for the delivered scope.

Integration documentation and relevant tests.

We define the API contract and business rules, implement the operations, and check them with the application or integration that will use them.

Share your backend or product requirements, data model, access rules, and external API documentation where relevant.
