Backend & API development.
The systems behind the interface. APIs, databases and infrastructure built around your product's data and operations.

The part everything depends on.
For a product that needs a new backend, a documented API or changes to an existing system. Bring the clients, data flows and operational constraints it must support.
- Data & contracts
- Data models, validation rules and API behaviour, including errors and permissions.
- Application logic
- Authentication, background work and integrations, with failure handling matched to the workflow.
- Operations
- Deployment instructions, configuration and an agreed plan for logs, backups and recovery.
Define the contract before the endpoint.
An endpoint name does not describe an API. We specify who can call it, which data it accepts, what it returns and how callers distinguish invalid input from a temporary failure.
The data model follows ownership and lifecycle. Who can create a record, how long does it remain useful, which systems reference it and what should happen when it is deleted? These choices shape migrations and application behaviour.
Make failure visible and recoverable.
Background jobs and external services do fail. We define timeouts, retry boundaries and how an operator can identify work that has not completed. Logs should explain an event without exposing credentials or unnecessary personal data.
Infrastructure choices follow the workload and the team's ability to operate it. Capacity assumptions, backup scope and recovery steps are documented. A stack is not selected because it looks impressive on an architecture diagram.
Keep existing clients in view.
Changing a backend can break mobile apps, integrations or internal tools that are not deployed at the same time. We identify those dependencies before altering contracts or data formats.
For a new build, handover includes the custom source, configuration guidance and API documentation. For an existing backend, we also describe compatibility decisions and the deployment sequence needed to make the change safely.
A few things to know.
Can you extend an API without replacing it?
Often, yes. We review the current contract, callers and data model first. The proposal describes compatibility requirements and any migration work.
Is hosting included?
Infrastructure setup can be part of the build. Hosting fees and ongoing operations are separate items that must be identified in the proposal.
Do you hand over infrastructure access?
Account ownership and access are agreed before deployment. The handover covers the custom source and the information needed to operate the agreed environment.
